Abstract:
Researches of multiplecomponent (TiNiMo)Nb alloys with 0.5, 1 and 1.5 at.% Nb. Experimental dependences of strain accumulation and recovery at multiple SME have showed a hysteresis behavior in all the studying alloys at temperature changing. A growth of hysteresis characteristics with an increase in Nb content was established. The quantities microanalysis let to identify the following structure of (TiNiMo)Nb: matrix on the base of intermetallic compound В2 – TiNi; eutectic, NiTiNb and Ti2Ni phases. In the study of structure revealed that NiTiNb particles are local obstacles that cause the increase of hysteresis width.
