Abstract

One or more substitutional elements may be used to reduce the solution treatment temperature and required quench rates for hardening of 60-NITINOL. The advantages of modified NITINOL include that less energy is consumed during the heat treatment process, the material is subjected to less thermal distortion, and less machining is required. Modified NITINOL may have adequate hardness for bearing applications and may display highly elastic behavior.
