Study of Intermetallic Compounds.

Abstract

This report describes results of mechanical property tests and microstructure studies on a series of alloys based on the intermetallic compounds Ti3Al (alpha 2) and TiAl (gamma). This class of alloys has shown considerable promise for high temperature applications and the objective of this program has been to study the microstructure of a series of alloys containing both the alpha 2 and gamma phases with a view to improving the mechanical properties. It has been shown that a variety of microstructures can be produced in a Ti-26% Al - 10% Nb base alloy, either by addition of ternary and quaternary alloying elements, or by heat treatment.
