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%

Deoxidization effect research of a new Al based complex deoxidizer
工程科学学报, 2015 As a deoxidizer for steelmaking,Al has a problem of oxidation loss when it is added into liquid steel,which leads to a lower utilization rate of Al. At the same time,the high melting point and irregular shape of the deoxidization products make it difficult to remove Al2O3 inclusions from molten steel effectively,which causes nuzzle clogging and steel ...
