The common matrix alloys of magnesium matrix composites are traditional commercial magnesium alloys such as AZ series alloys [4,5]. The large number of coarse second phases formed in these as-cast commercial magnesium alloys could act as cracks initiation and reduce the mechanical properties of the corresponding magnesium matrix : K.B. Nie, Z.H. Zhu, K.K. Deng, J.G. Han. The capability of backward extrusion (BE) method was assessed to achieve modified structures in AZ80 magnesium alloy. At first, 3D-Deform was employed to simulate the deformation flow through the deformed cup which gives an evidence from the flow behavior of the material. The material was processed via BE method at various temperatures of , , and ° by: The objective of this paper was to investigate the influence of magnesium on microstrructural changes and mechanical properties such as tensile strength and hardness of the Al4Cu alloys. The modifications of Al4Cu by adding Mg of to 2 % in the interval of % mixing with stirrer and castedFile Size: KB. K. Hirai et al.

The mechanical properties of the alloys became rapidly worse upon annealing between and ℃. H aluminum alloy became sensitized and susceptible to intergranular corrosion at an annealing temperature of ℃ for 48 h. The distribution and shapes of β-phase particles markedly affected the sensitization. The effect of magnesium addition up to wt.% on the microstructure and mechanical properties of Al-9SiMn alloy has been investigated in both as-cast and heat treated conditions. Effects of neodymium (Nd) on the microstructures, mechanical properties, in vitro corrosion behavior, and cytotoxicity of as-cast Mg-1Mn-2Zn-xNd alloys (x = , , , mass%) have been. The addition of Ca can improve the tensile properties of alloys at room temperature. When the content of Ca is 2%, good properties are obtained, the tensile strength and yield strength of Mg-6Zn-2Al-2Ca alloy reaches MPa and MPa respectively.
When the influence of the alloying elements on the mechanical properties of the homogenized alloys are investigated, it is found that tensile strength, ductility, and toughness of the homogenized alloys increase with the amount of Zn in the alloy. The reason for this increase is that Zn has a solution hardening effect on magnesium alloys. On. "This book is the first to provide readers insight into the science, characteristics, and applications of current and futuristic magnesium-based materials, with particular emphasis placed upon the properties of magnesium-based composites and the effects of different types (metallic, ceramic, interconnected and intermetallic) of reinforcements from micron length scale to nanometric length . This study investigates the effect of artificial aging treatment and mechanical attrition treatment on the corrosion behavior of Al alloy in Red Sea environment. The artificial aging of the alloy is carried out at temperature range °C–°C in steps of 20°C for various time periods after the solution heat treatment at °C for 1 hour. The previous study conducted on the as-cast Mg-2Y-1ZnZr alloy showed that the tensile strength, yield strength and elongation of the as-cast alloy were MPa, MPa and %, respectively. In order to further explore the potential of the material, the hot extrusion process of variable temperature ( °C, °C and °C) was carried out on the basis of the as-cast alloy.
