摘要	The microstructure and stress-strain behavior of porous Ni-Ti intermetallics fabricated by powder sintering of Ni, Ti and/or TiH2 are investigated. The pores are small and well distributed in the present porous Ni-Ti alloys and the phase constituent and stress-strain behavior of porous Ni-Ti alloys are significantly influenced by the sintering conditions (sintering temperature and sintering time) and TiH2 additions. With increasing sintering temperature, the pseudoelasticity (PE) increases while the hysteretic width decreases. A second compression also leads to an increase of PE, elastic modulus and related deformation resistance. Further, the stress-strain behavior of porous Ni-Ti alloys is different in some way from that of bulk Ni-Ti alloys and other porous materials. (C) 2000 Elsevier Science Ltd. All rights reserved.
