High Temperature Texture Strengthening in Zinc.

摘要

The authors have investigated the compressive creep behavior of zinc over a wide range of temperatures and strain rates as part of an investigation of zinc-based particulate composites. The purpose of this note is to illustrate the large anisotropy in strength observed by the authors in the textured zinc sample and to compare the results with other high temperature creep data reported for polycrystalline zinc. The salient feature of the results was the following:for the entire range of testing,samples deformed by uniaxial loading parallel to the extrusion axis were consistently 1.5to 2times stronger than samples deformed by loads applied parallel to the extrusion axis.
