ELECTRON THEORY STUDY ON THE OXIDATION BEHAVIOR OF Ti 3Al
|
Abstract:
According to the EET, the valence electron structures of Ti 3Al alloy effected by oxygen have been calculated . The results showed that the bond structres of Ti 3Al alloy were very seriously anisotropic due to the dissolved oxygen in crystal cell of Ti 3Al,which resulted in very serious embrittlement . The formation of TiO 2 is more harmful in forms of ductility and oxidation resistance than that of Al 2O 3 with possessed stronger bond and higher heat stability. The measures to improve oxidation resistance of Ti 3Al by alloying are proposed.
