Abstract

The microstructural development in a Ti3Al alloy modified with an addition ofil w/o Mo has been studied. Under equilibrium conditions (arcmelted) a two phase ordered hexagonal and ordered bcc structure is present. Evidence of omega phase was alsoobserved. By rapid solidification the hexagonal structure is suppressed, which contrastswith the behavior of a Ti3Al alloy modified with a similar amount of Nb. The mechanism by which the phases present form is discussed in terms of the atomic movements required.
