Zhao, X.; Neves, Filipe; Correia, J.B.; Liu, K.; Fernandes, F. M. Braz; Koledov, V.; von Gratowski, S.; Xu, S.; Huang, J.ABSTRACT: This work reports on an efficient powder metallurgy method for the synthesis of NiTi alloys, involving mechanical activation of pre-alloyed NiTi2 and elemental Ni powders (NiTi2-Ni) followed by a press-and-sinter step. The idea is to take advantage of the brittle nature of NiTi2 to promote a better efficiency of the mechanical activation process. The conventional mechanical activation route using elem...
