Effect of Ecap by Routes B c and C on the Microstructure and Temperature of Martensitic Transformation of NitiNb Alloy

  • Published:
Metal Science and Heat Treatment Aims and scope

The structure of a NiTiNb shape memory alloy is studied after equal channel angular pressing (ECAP) by routes B c and C. The mechanisms of straining of the alloy after the ECAP are analyzed. The temperatures of martensitic transformations are determined by the method of differential scanning calorimetry as a function of the route of the ECAP.
