The alloys were produced under a controlled atmosphere by a squeeze-casting process. After casting of the various magnesium alloys, the samples were produced for mechanical and metallographic examinations.The results show that adding alloying elements effectively modifies the microstructure of AM60 alloy. The addition of alloying elements led to a decrease and to an increase. A similar trend is also observed in the alloys for corrosion behaviors.

The Effect of strontium on the microstructure and mechanical properties of Mg-6Al-0.3Mn-0.3Ti-1Sn”
Journal Papers Journal of Magnesium and Alloys 2 (2014) Page 214-219.
Abstract
In this work, the microstructural and mechanical properties of the certain magnesium-based alloys were investigated. The alloys were produced under a controlled atmosphere by a squeeze-casting process and characterized by optical microscopy (OM), scanning electron mi- croscopy (SEM), an energy-dispersive spectrometer (EDS) and X-ray diffraction (XRD) analysis. The results indicated that the addition of strontium element modified the structure and refined the grain size. The hardness and yield strength of the alloys increased continuously with increasing strontium content, while the elongation was gradually decreased. Also, the tensile strength value of the based alloy was increased by adding Sr up to 1 wt.%. After more addition of Sr, the tensile strength starts to diminish.
The effect of silver on wear behaviour of zinc-aluminium-based ZA12 alloy produced by gravity casting
Journal Papers Materials Characterization 89 (2014) Page 81-87.
The aim of this study was to investigate the effect of different weight concentrations of silver (0.1, 0.3, 0.5 and 0.7 wt.%) on the microstructure, hardness and wear properties of the gravity cast zinc–aluminium based alloy ZA-12. The alloys were manufactured under nitrogen protective atmosphere by a gravity casting process. Metallographic studies reveal that the addition of silver to the standard ZA-12 alloy changed the volume fraction and structure of the primary β-dendrites in the ZA-12 alloy. Also, it was observed that the addition of silver to ZA12 alloy enhanced the hardness and wear properties effectively. However, the corrosion resistance was decreased with increasing silver content. In addition to this, the highest hardness value among experimental alloys was obtained for the alloy containing 0.7 wt.% Ag with 116 HB. The wear rate for all applied loads is decreased with rising silver content. A similar trend was observed for the friction coefficient. The alloy containing 0.7 wt.% Ag exhibited the highest wear resistance at all loads.
Addition of Strontium to an Mg-3Sn Alloy and an Investigation of its Properties”
Journal Paper Materials and Technology ,Vol. 473 ,2013, Page 135 – 137.
Abstract
The effect of strontium additions in mass fractions of (0.05, 0.1, 0.2, 0.5 and 1) % to a magnesium alloy (Mg-3Sn) was investigated in this work. The alloys were gravity cast under a controlled atmosphere. The mechanical properties and the microstructures of the above alloys were examined and recorded. The results revealed that an addition of strontium to the above alloy had significantly affected its microstructure. The X-ray diffraction results showed that in all of the obtained alloys the main phases were -Mg and Mg2Sn, and that the strontium-based intermetallics were not detected. The hardness values increased with the increasing strontium content. The highest yield strength, tensile strength and elongation were exhibited by the Mg-%3Sn-%0.1Sr alloy.
Influence of silver addition on the microstructure and mechanical properties of squeeze cast Mg-6Al-1Sn-0.3Mn-0.3Ti”
Journal Paper Journal of Alloys and Compounds Volume 509, Issue 27, 2011, Pages 7368-7372.
Abstract
In this study, the effect of silver (0, 0.2, 0.5, and 1 wt.%) on the microstructure and mechanical properties of a magnesium-based alloy (Mg–Al 6 wt.%–Sn 1 wt.%–Mn 0.3 wt.%–Ti 0.3 wt.%) were investigated. The alloys were produced under a controlled atmosphere by a squeeze-casting process. X-ray diffractometry revealed that the main phases are -Mg, -Ti, -Mg17Al12 and Al8Mn5 in the all of alloys. In addition to, Al81Mn19 phase was found with Ag additive. Besides, the amount of-Mg17Al12 phase was decreased with increasing the amount of Ag. The strength of the base alloy was increased by solid solution mechanism and decreasing the amount of -Mg17Al12 phase with addition of Ag. Furthermore, existence of Al81Mn19 phase can be acted an important role in the increase on the mechanical properties of the alloys.
Influence of titanium and chromium addition on the microstructure and mechanical properties of squeeze cast Mg–6Al alloy”
Conference Papers Journal of Alloys and Compounds, Volume 509, 2011, Pages 3190-3196
Abstract
In this study, the effect of titanium and chromium (0, 0.1, 0.2, 0.3, and 0.4 wt%) on the microstructure, mechanical and wear properties of a magnesium-based alloy (Mg–Al 6 wt%) were investigated. The alloys were produced under a controlled atmosphere by a squeeze-casting process. The results show that the addition of Ti element modified the structure and decreased the grain size. A similar trend is also observed in the alloys containing Cr. The results of hardness, tensile and impact testing indicate that the hardness, tensile and impact strength of Mg–6Al alloy increased by adding Ti up to 0.2 wt% and then is relatively constant with increasing Ti. A similar result is also observed in the alloys containing Cr. The wear rate of Mg–6Al alloy decreased with increasing alloying elements up to 0.2 wt%. Then the wear rate is relatively constant with the addition of more alloying elements. While the friction coefficient value of Mg–6Al alloy gradually increased with increasing Cr, the friction coefficient value of Mg–6Al alloy decreased with increasing Ti up to 0.2 wt%. Then the friction coefficient value is constant with increasing Ti.
The effect of tin addition on the microstructure and mechanical properties of squeeze cast AM60 alloy”
Journal Paper Journal of Consumer Psychology, Volume 22, Issue 2, April 2012, Pages 191-194
Abstract
In this study, the effect of tin addition (0, 0.5, 1, 2 and 4 wt% Sn) on the microstructure and mechanical properties of a magnesium-based alloy (AM60) were investigated. The alloys were produced under a controlled atmosphere by a squeeze-casting process. The results indicated that Sn addition effectively decreased the dimension of eutectic phase region on the grain boundary. The hardness value of AM60 alloy increased with the increment of alloying element ingredients. The tensile testing results indicated that the greatest ultimate tensile strength (UTS) was exhibited by AM60–4 wt% Sn as 212 MPa. The impact strength of AM60 alloy was remarkably increased by 0.5 wt% Sn addition from 16 J in initial state to 24 J. Having added to this critical weight percentage tin ratio, the impact strength starts to decrease with increasing Sn addition.
Comparison of the wear properties of modified ZA-8 alloys and conventional bearing bronze”
Journal Paper Materials and Design, 2007/03 Volume 28, Issue 6, Page 1889-1897
Abstract
In this study, an attempt has been made to examine the wear response of some modified Zn–Al based alloys and a conventional bear- ing bronze (SAE 660) at the sliding speeds of 0.5 ms1, 1 ms1, 1.3 ms1, 1.7 ms1 and 2 ms1 using applied load of 30 N and 45 N. The standard ZA-8 alloy and modified with 1% Pb, 1% Sn and 1% Cd alloys have been subjected to a pin-on-disc wear test under dry con- dition. A conventional bearing bronze has also been subjected to identical tests with a view to assess the working capability of the mod- ified Zn–Al based alloys with respect to existing ones. The results have shown that the ZA-8 alloy and modified with Pb, Sn and Cd alloys revealed higher wear resistance when compared with bearing bronze. In addition, wear resistance of ZA-8 based alloys increased with increasing sliding speed up to 1.7 ms1 for 30 N and 1.3 ms1 for 45 N, respectively. But it decreased with increasing sliding speed. The addition of Pb to the ZA-8 alloy increased wear resistance of the alloy for all of the sliding speeds at 30 N and 45 N, while the addi- tion of Cd increased wear resistance of the ZA-8 at 45 N. But Sn alloying element caused worse wear resistance for ZA-8 alloy. On the other hand, the friction coefficients of ZA-8 and modified alloys are higher than that of the bearing bronze. Metallographic studies showed that the addition of Pb, Sn and Cd resulted in modifying on the microstructure of ZA-8 alloy.

Properties of Alumina Particulate Reinforced Aluminum Alloy Produced By Pressure Die Casting”
Journal Paper Materials and Design Volume 27, Issue 8, 2006, Pages 676-683
Abstract
In this study, metal–matrix composites of an aluminum–silicon based alloy (LM6) and Al2O3 particles with volume fractions of 0.05, 0.10 and 0.15 and in size of 44, 85 and 125 lm were produced using pressure die-casting technique. Density, hardness, tensile strength and wear properties were examined. The density values of the composites increased by adding Al2O3 particle. The hardness of the composites increased with increasing particle volume fraction and with decreasing particle size. The tensile strength of the composites decreased with increasing particle volume fractions and size. The wear rate of the composites decreased with increasing particle volume fraction and with decreasing particle size but increased proportionally to the applied load. Wear mechanism for the surface of the unreinforced alloy was plastic deformation, whereas for the composites it was the layer deformation on the surface of the composites.

The Effect of Ti–B and Sr on the mechanical behaviour of the Zinc–Aluminum-based ZA-12 alloy produced by gravity casting”
Journal Paper International Journal of Materials Research 2006/08, Page 1152-1157
Abstract
In this study, the effect of Ti–B (0.05–0.7 wt.% Ti, 0.01–0.13 wt.% B) and Sr additions (0.05–0.7 wt.%) on the hardness, ultimate tensile strength (UTS), strain and fatigue properties of the gravity cast Zn–Al-based ZA-12 alloy was investigated. While the Ti–B additions had no significant effect on the hardness of the alloys, the Sr additions lowered the hardness by a small amount. UTS and fatigue resistance of the ZA-12 alloy increased with 0.05 wt.% Ti, but the addition of 0.05 wt.% Sr to the standard alloy did not change these properties significantly. In excess of 0.05 wt.% Ti and Sr, the UTS and fatigue resistance of the alloys decreased and reached a lower value than that of the standard alloy. The failure strain only increased for the ZA-12 alloy containing 0.05 wt.% Ti, then decreased with further increase in Ti content. The failure strain values of the alloys decreased with addition of Sr. Metallographic examination indicated that the addition of Ti–B strongly modified the microstructure of the standard ZA-12 alloy, but Sr did not. Ti and Sr have also formed complex shaped intermetallic compounds, which were identified as Al5Ti2Zn and Zn5Al3Sr by X-ray diffraction and EDS analyses. It can be suggested that these particles cause a decrease in UTS, fatigue resistance, and strain of the ZA-12 alloy.
