Plasticy of close packed long-range ordered Cu-Zn-Al shape memory alloys

Abstract

The critical rasolved shear stress (CESS) for plastic deformation of Cu-Zn-Al martensitic single crystals with an electron concentration has been determined as a function of temperature between 80k and 170k. It has been found that below room temperature the CRSS depends little on temperacure, but that above this temperature it increases with T.
