摘要：

TiH2 powder is added as a pore-forming and active agent in synthesis of porous Ni-Ti alloys by using a conventional powder sintering technique. The influence of addition of TiH2 on microstructure, memory characteristics and pseudoelasticity (PE) of porous Ni-Ti alloys is investigated. It is found that porous Ni-Ti alloys produced with or without addition of TiH2 exhibit good memory effect and PE, and the addition of TiH2 not only has a pronounced effect on the microstructure but also increases the shape memory effect (SME) and volume memory effect of porous Ni-Ti alloys. Further, the addition of TiH2 has a significant influence on the elastic behavior and Young's modulus of porous Ni-Ti alloys. (C) 2000 Elsevier Science S.A. All rights reserved.
