Abstract

Sintered tungsten base heavy alloys made of tungsten grains embedded in a nickel rich matrix can possess low room temperature ductility that may be improved by subsequent heat treatment. The sintering thermal cycle was simulated by a finite element procedure, and it was found that the vast differences in thermal and elastic properties of the microstructural components result in significant residual interfacial strains upon cooling to ambient temperature. These strains may contribute significantly to the low room temperature ductility of this class of liquid phase sintered alloys and should be relieved in order to improve ductility.
