Self-propagating high-temperature synthesis (SHS) of porous parts using nanocrystalline NiTi

Porous Nickel Titanium (NiTi) shape memory alloy (SMA) is a promising material for use in applications such as biomedical implants. It has effective damping characteristics to shock by utilizing the energy absorption capabilities. Conventional methods such as the sintering process, hot isostatic pre...
