The Effect of Sintering Temperature and High Energy Mechanical Milling Time on Microstructure and Mechanical Properties of the TiAl Alloy Fabricated by Pulse Current Activated Sintering.

摘要

The attractive properties of TiAl alloy are high specific Young's modulus, strength, good oxidation and superior burn resistances [1, 2]. Due to these excellent properties, TiAl alloy have widely been researched for making part of gas turbines, aerospace and automotive application to replace nickel based super alloys and titanium alloys. However, their room temperature ductility and elevated temperature formability were not satisfied to widely use.
