Abstract
This article evaluates the creep behavior of nickel aluminides, titanium aluminides, and molybdenum disilicides and their composites as a function of stress and temperature. Significant improvements in creep strength were achieved in NiAl by the addition of HfC dispersoids, and in MoSi2 and its alloys through the addition of SiC whiskers or particulates. On the basis of creep resistance, molybdenum disilicide alloys and their composites have a high potential for application at temperatures greater than 1,000°C, and they are also potential competitors to more brittle ceramic-ceramic composites.
