Nitinol’s martensite inelasticity diagramm for tension, compression and tension after compression

, ,

Abstract:

Uniaxial tension and uniaxial compression experiments have been carried for specimens of circular cross-section from the Nitinol that is located in a fully martensitic phase state, and uniaxial compression tests on samples of the material which has been subjected to pre-stretch up to different degrees of deformation. The results of the tensile tests are compared with similar data for samples from flatten wire (the same material). Investigated the questions of the tension and compression diagrams and influence of the value of the preliminary tensile strain on a chart form subsequent compression diagram, which is important to describe the isotropic and kinematic hardening shape memory alloy.
