The process of controlled laser sintering for powdered SHS compositions with the bases Ni-Ti and Ni-Al was realized. The optimal parameters of laser effect, under which the reaction of SHS proceeds in controlled regime, were determined. The phase composition of the sintered structure was revealed by the x-ray phase analysis. In particular, it was shown, that the NiTi-material with shape memory effect, perspective for using in medical implantation, is the basis for forming intermetallic phase under laser sintering of Ni_Ti powder compositions.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
