Formation of a dendrite structure in crystals NiFeGaCo alloy in the process of growing by the Stepanov method

The process of growing crystals the NiFeGaCo alloy by Stepanov method has been developed. It was found that structural perfection is disturbed formation dendrites, which are distributed inhomogeneously both along length and in cross sections crystals. blocking effect dendrites on growth martensite phase, appears when samples cooled to temperature transition crystal state, found. elemental composition dendritic formations studied it shown iron content dendrite approximately 30% higher, gallium 40% lower than matrix. Based modeling heat transfer processes real zone, taking into account experiments performed, recommendations were obtained for suppressing Keywords: Dendritic structure, shape memory alloys, Stepanov's method.
