Article Preview

Porous TiNi shape-memory alloy (TiNi SMA) bodies were produced from the (Ti+Ni) powder mixture by self-propagating high-temperature synthesis (SHS) method. Various processing variables such as ignition temperature and heating schedule were used to control the pore structure. Relationship between pore structure and mechanical property was also investigated. An in vivo test was performed to evaluate bone tissue response and biocompatibility of porous TiNi SMA. It showed no apparent adverse reactions such as inflammation and foreign body reaction. Bone ingrowth was found in the pore space of all implanted blocks. Introduction Titanium-nickel intermetallic compound is well known as one
