Abstract
A mechanism by which the macroscopic stress redistributes among oriented grains of CuAlZnMn shape memory alloy polycrystals transforming pseudoelastically in tension/compression has been studied experimentally by in-situ neutron diffraction techniques. Micromechanics model simulations for pseudoleastically deforming Cu-based alloys and NiTi are presented and the results are compared with the diffraction data. Key factors controlling the load partition are found to be the elastic anisotropy of the austenite phase, crystallographic type of the martensitic transformation and associated transformation anisotropy, grain size, texture and sense of the applied uniaxial load.
