Abstract
The annealing textures were analyzed by means of an ODF software in an Fe–27Mn–6Si–5Cr alloy wire annealed at various temperatures from 873∼1223 K. At the same time, the shape-recoverable degrees of the wire specimens were measured by tensile strain at room temperature followed by recovery heating. A nearly unique ⟨001⟩ texture appears in the wire specimen annealed at 973 K, in which the highest shape recovery ratio is obtained. A synthesis orientation factor S has been definded as a parameter for estimating the tendency for polycrystalline materials to stress-induced martensitic transformation. The reason for the influence of texture on the shape memory effect is discussed.
