Young Modulus, Maximum Real Stress and Elastic Deformation Limit of W and WSi from Statistical Moment Method

Abstract

We present the theory of nonlinear and elastic defomation for BCC metal and binary interstitial alloy builded on the basis of a statistical moment method and our numerical calculations for W and WSi depending on temperature, pressure and interstitial atom concentrations. Our numerical calculations for Young modulus of W are compared with experiments and our other numerical calculations are new and predictic.
