Abstract

The fiber textures for various annealing temperature were determined by XRD and analyzed by means of orientation distribution function (ODF) software in an Fe-27Mn-6Si-5Cr alloy wire. At the same time the shape recoverable degree of the wire specimens annealing at different temperatures from 873 to 1223K was measured by tensile strain at room temperature after heating to recover A nearly unique texture appears in the wire specimen annealed at 973K, in which the highest shape recovery ratio is obtained correspondingly. The reason concerning the influence of the texture on the shape memory effect is discussed.
