Title: Localized obstacles to low temperature dislocation motion in bcc tungsten

Abstract

There has been great concern in the last two decades with understanding the limits of dislocation motion and therefore ductility, in bcc metals. The effect of interstitial elements is known to be quite important in controlling macroscopic flow in tungsten, but current understanding of the microscopic processes is limited. The present investigation examines the localized obstacles to dislocation motion in tungsten single crystals from 4.2° to 298°K using a compressional microstrain technique.
