By the hot isostatic pressing process (HIP), parts close to the net shape are produced and the second operation may no longer be required. In this study, the effects of mechanical alloying on NiTi alloy produced by the HIP process were investigated. The starting powders of the first group were mechanically alloyed. The starting powders of the second group were mechanically mixed. Afterwards, the microstructures, transformation temperatures and some mechanical properties of these two groups were compared. For these examinations, SEM-EDS, XRD, DSC analyzes and microhardness measurement, density measurement by hydrostatic weighing method were performed. The result showed, mechanical alloying causes a more homogeneous microstructure and higher transformation temperatures.falsehot isostatic pressing | mechanical alloying | NiTi | shape memory alloy | transformation temperatureArticle10.3103/S106782122203013010.3103/S10678212220301302-s2.0-85133430221WOS:000821035400011336343631934-970X
