Mechanical Behavior of Titanium Alloys (Formation Behavior of alpha/beta Interface Phase in Ti-6Al-4V.

Abstract

The conditions for formation of the interface phase, or interfacial layer, in Ti-6Al-4V have been studied systematically. The interface phase does not grow during isothermal treatments, but rather only during cooling from elevated temperatures to about 650 deg C. The width of the interfacial layer is a function of the cooling rate, having a maximum of about 4000A at 28 deg C/hr. The interface phase forms initially with an fcc structure which subsequently transforms to hcp alpha phase. A theoretical description of the mechanisms of interface phase formation is presented.
