Annotation	The cobalt-based shape memory alloys (SMA) are expected to be the new kind of so-called ferromagnetic SMAs. The structure of the investigated material Co38Ni33Al29 is composed of two phases – an B2 ordered matrix (Co,Ni)Al and a disordered face centred cubic cobalt solid solution, γ-phase. The B2 phase matrix undergoes martensitic transformation into the tetragonal L1_0 structure. The growth of two-phase unidirectional structures was described. The first results of the interaction between martensitic variants and non-transforming particles in the structure are presented.
