Abstract
An Electro-Discharge Compaction (EDC) process has been developed to consolidate the intermetallic compound TiAl from the compact of atomized TiAl powders. The EDC process was performed by subjecting high voltage(-15KV). high density electric current from a capacitor bank of 350μF to the compact tinder a pressure of 40MPa. The TiAl compound of 97% density with bending-strength of G2.8kgf/mm2, Vickers micro-hardness of GGOHv, grain size of 32nm was obtained.
