Paper Title:
Preparation of High-Porosity NiTi Alloys by Powder Sintering with NaCl Pre-Forming
  Abstract

High-porosity NiTi shape memory alloy has pseudo-elasticity and shape memory effect for energy absorption and convenient on-line repair without replace. In this paper, high-porosity NiTi alloys with interconnected and well distributed pores were fabricated successfully by sintering, using NaCl as temporary space-holders. Optical microscope, SEM and XRD have been used to investigate the porosity and pore structures. The results show that porosity can be up to 88%.The size and porosity of the pores depend mainly on the addition of salts in the compacts, and are also related to temperature and forming pressure.
