Research Abstract

The transformation-start and -finish conditions are identified in an Fe-based shape memory alloy by carrying out the tension/compression-torsion tests of thin-walled tubular specimens.
The martensite-start condition determined in the isothermal proporional loading is represented by the ovalshape curves on the axial stress-shear stress plane, thus being different from the von Mises yield condition in plasticity. The temperature effect is isotropic. The third invariant of the stress should, therefore, be taken into account when constructing a transformation thermomechanical theory.
The austenite-start condition (the reverse transformation-start condition) is represented by a plane in the stress-temperature space. The direction of its unit normal depends on the direction of the pre-stressing, meaning on the type of the martensite variants induced in the pre-stressing process. When several types of variants are induced during pre-stressing, a polygonal cone is formed to represent the austenite-start condition in the stress-temperature space. The position of the plane in the stress-temperature space is governed by the amount of the variants.
