Several techniques were used to investigate the chemical and phase composition of four trial batches of nitinol powder produced by calciothermic reduction as well as their morphology and granulometric composition. Almost all powders produced by a similar procedure contained an allowable amount of impurities and were practically free of minor detrimental phases such as Ti₂Ni and Ni₃Ti. The powders under study have gamma or lognormal particle size distributions and spongy particles morphology typical of this production method. The tap density over 3g/cm³ was achieved at least in one case, which gives us an opportunity to successfully produce bulk articles by subsequent treatments such as sintering or hot isostatic pressing.
