Deoxidation of Titanium Aluminides.
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1993 The deoxidation of TiAl is one of the key technologies to recycle the scrap contaminated through the casting processes. Fairy high amount of aluminum, more than 30%, enables the few deoxidation methods such as evaporation of aluminum oxide or Ca addition, while they are inapplicable to conventional Ti-alloys containing lower aluminum.The TiAl with 0.21%
