Microstructure of NiTi shape memory alloy due to tension-compression cyclic deformation

Journal Article Xie, Z ; Liu, Y ; Humbeeck, J van - Acta Materialia

Experimental results have shown that, during mechanical cycling under tension-compression load within {+-}4% strains, the NiTi shape memory alloy is cyclic strain-hardened. The maximum stresses under both tension and compression increase with increasing number of cycles and tend to stabilize with further cycling. The present work is focused on the martensite microstructure developed as a result of mechanical cycling. TEM observations show that, before cycling, the martensite variants are well self-accommodated to each other with the <011> type II twinning as the main lattice invariant shear. After mechanical cycling, the martensite plates are still self-accommodated and the (11{bar 1}) typemore »« less

In situ, 3D characterization of the deformation mechanics of a superelastic NiTi shape memory alloy single crystal under multiscale constraint

Journal Article Paranjape, Harshad M. ; Paul, Partha P. ; Amin-Ahmadi, Behnam ; ... - Acta Materialia

Microstructural elements in NiTi shape memory alloys (SMAs) – precipitates, phase boundaries, inclusions, grain boundaries – can be viewed as sources of multiscale constraint that influence their deformation response. In this paper, we characterized in situ, and in 3D, the deformation and the evolution of microstructure during a tension test in a superelastic NiTi specimen containing some of these sources of constraint. The method used was far-field high-energy X-ray diffraction microscopy (ff-HEDM), complemented by electron microscopy. We simulated the local stress state in the specimen using a microstructural model informed by the experimental data. Using these combined microstructure, deformation, andmore »« less
