摘要：
The wire drawing conducted in the R-phase of TiNi shape memory alloys shows that the drawing stress in the R-phase is lower than that in the parent B2, phase and B19' martensite. This feature is ascribed to the R-phase having lower shear modulus. The martensite can be stress-induced by cold drawing in the R-phase. The cold drawing and subsequent annealing conducted in the R-phase can significantly affect the transformation temperatures and transformation heats of the drawn wires. (C) 2000 Elsevier Science B.V.
