Introduction Magnesium alloys are expected to play an important role in next-generation materials, which have possibilities of contributing to reducing the total product weight when magnesium can be used to replace aluminum and mild steel.
When alloyed, magnesium has the highest strength-to-weight ratio among the metallic materials for structural applications.
Moreover, because of the ease of recycling of metallic materials, magnesium has received global attention from the standpoint of environmental protection [1].

High chemical reactivity with cutting tool materials is resulted due to combination of hardening tendency with low thermal conductivity of the alloy.
Materials and Methods All of specimens were prepared from Ti-53Al intermetallic compound billets produced by Vacuum Arc Remelting (VAR) method.
