Study on the oxidation and corrosion properties of titanium aluminide from a microstructural viewpoint by Chan, Shao Wei

“…Several alternative methods of fabrication have been put forward, with powder metallurgypossessing the highest potential to overcome the short comings of casting.In this study, different ball milled samplesof the same composition was prepared, and their subsequent microstructure, corrosion,and oxidation behaviour after Spark Plasma Sintering(SPS)was investigated.Samples that were subjected to SPS with increasing ball milling parameters yielded increasing γ-TiAl phase and decreasingα2-Ti3Alphase. …”
