Abstract Importance of creep properties in evaluating heat resistant characteristics of intermetallics is first demonstrated. Compressive creep behavior of single-phase γ-TiAl polycrystals (50–53.4 mol.% Al, 20–200 μm) at 1000–1200 K under 100–400 MPa is summarized. Creep behavior can be classified into two types, and minimum creep rates are shown as

Abstract Ordered intermetallic alloys based on the stoichiometric iron aluminide compositions of Fe3Al and FeAl are being actively considered for high-temperature structural applications. They exhibit poor room temperature ductilities due to hydrogen embrittlement. Surface passive films reduce embrittlement by lowering the rate of hydrogen liberation

B2 aluminides are potential high temperature structural materials because of their low densities and excellent oxidation resistance (1). B2 NiAl and FeAl are of particular interest because of lack of strategic elements in these alloys. The phase diagrams containing these two ordered structures are illustrated in Figures 1 and 2.

Titanium Aluminides - An Overview
MRS Proceedings, 1984The object of this paper is to describe a coordinated research and development program which has been pursued by an Air Force-Industry-University team for more than twelve years. The focus of our attention has been on the development, processing, and engine testing of alloys based on intermetallic compounds, specifically on the aluminides of titanium ...

Development of Iron Aluminides
1987Abstract : This program addresses the development of iron aluminide base alloys by rapid solidification and the determination of their potential for use in aircraft turbine engines as alternatives to high chromium steels and nickel-base alloys. The program was divided into three tasks.

Titanium Aluminide Intermetallics
2012Abstract Titanium aluminides are lightweight materials that have relatively high melting points and good high-temperature strength. They also tend to be stronger and lighter than conventional titanium alloys, but considerably less ductile.
