High Temperature Creep and Fracture Behavior of the Refractory Metals

  • Conference paper
Refractory Metal Alloys Metallurgy and Technology

Abstract

The creep properties of the pure, polycrystalline refractory metals are reviewed and summarized. The creep behavior of all the pure metals is correlated in terms of their diffusivities and elastic moduli following the Sherby-type analysis. Experimental values of the activation energy and stress dependence of creep are also summarized for the pure metals, and the structural features of deformation and fracture are described. The general effects of alloying are delineated in terms of solid solution, dispersed phase, and strain hardening contributions to high temperature creep strength.
