The results of martesitic transformation (MT) and shape memory effect (SME) in quaternary Ti50(NiCoCu)50’ Ti50(NiFeCu)50 and (TiAl)50(NiCu)50 alloys studies arc generalized in this paper. On alloying TiNi simultaneously by two elements, their individual effect on MT and SME is conserved. Martensitic transformations B2→R and B2→B19' are almost simultaneously realizing in a binary TiNi. One can selectively control each of two MT channels by selecting property of alloying elements. As a result, the alloys having any sequences of MT and their realizations temperatures, including simultaneous realization of two MTs at low temperatures, which was not observed earlier, can be produced.
