Abstract
NiTi powders were synthesized during high energy ball milling for 10 h. Highly dense nanostructured NiTi with a relative density of up to 99% was obtained within 1 minute by high frequency induction heated sintering under a pressure of 80 MPa. The grain size, microstructure, and mechanical properties of NiTi were investigated. The grain size and hardness of TiNi are about 122 nm and 590 kg/mm2, respectively.
Key Words
NiTi, nanostructure, sintering, mechanical properties
