Paper Abstract

Super elastic single crystal CuAlNi is one of the most popular shape memory alloys in the world. It has been widely used in engineering, biomechanics and medical science. But some of its basic properties such a martensitic transformation of CuAlNi single crystal under compression and also their generation, nucleation and propagation of transformation band are not competely investigated. Its mechancial properties of CuAlNi single crystal under compression are also not investigated completely. The deformation of CuAlNi shape memory single crystal is reported under compression loading for selected crystal orientation. The stress-strain curve is obtained when it is compressed. 2D microscope images of martensitic band are also observed clearly with special method. The deformation of CuAlNi shape memory single crystal of stress-induced martensitic transformation under compression was firstly studied by using IR camera. It demonstrates that the transformation band also exists under compression.
