Gas tungsten arc (GTA) surface modification process was used to deposit SiC particles and aluminum alloy powders on the surface of magnesium alloy AZ31. This method is an effective technique in producing a high performance composite layer. This process result notable grain refinement in the GTA surface modified composite layer. The hardness and wear resistance of the GTA surface modified composite layer are superior to that of as-received magnesium alloy AZ31. The hardness values and wear resistance of GTA surface modified composite layer depend on the GTA process parameters and the SiC particles powder concentration and distribution. The optimum processing parameters for the formation of a homogeneous crack/defect-free and grain refinement microstructure were established.

An attempt has been made to improve the surface hardness property of mild steel by developing a composite layer on the surface of mild steel using gas tungsten arc as heat source. Silicon Carbide was placed on the surface using a binder and heat was applied using gas tungsten arc. Variation of Silicon content with the weld current parameters was studied. The variation of microhardness with Silicon content on the surface was studied. Optimum parameter for attaining maximum surface hardness property using GTAW (Gas Tungsten Arc Welding) has been found.

The influence of initial texture and strain rate on the mechanical behavior, especially anisotropy and tension-compression asymmetry (TCA) in AZ31 was investigated. The results indicated that the TCA in AZ31 decreased as the strain rate increased, plastic anisotropy increased as the strain rate increased. After compression, the massive twins were observed in AZ31 samples compressed on the extruding direction, while the fraction of twins in samples compressed perpendicular to the ED was smaller.
