Resumo

The structure of a NiTiNb shape memory alloy is studied after equal channel angular pressing (ECAP) by routes Bc 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.
