Abstract

The adiabatic single-crystalline elastic constant of W-3 at.% Re and W-10 at.% Re were measured in the temperature range 77-298°K. The elastic anisotropy ratio, C44/C′, was found to follow the behavior predicted by Fisher for transition-metal alloys. Re additions to W decrease the elastic constant C′ which indicates decreasing stability of the bcc structure. This behavior is believed to be related to the d-band structure. The Debye temperature for alloys was calculated and found not to vary appreciably from the value for pure W.
