INTERNAL FRICTION STUDY OF INTERFACE DYNAMICS FOR STRESS-INDUCED I/C TRANSITION IN NiTi ALLOY
LI JIANGHONG and ZHANG JINXIUDepartment of Physics, Zhongshan, Guangzhou, China
Abstract
An internal friction peak and a minimum of modulus have been found in the process of stress-induced reversible incommensurate (I)/commensurate (c) transition in Ni-49 at% Ti alloy. The internal friction peak height Q-1 and modulus defect ƊM/M were associated with the I/c transition increase with increasing strain rate [MATH]. An explicit functional relationship between average velocity of I/c phase interface V and effective phase transition driving force ƊG/=ƊG-ƊGR was derived, with result V=V* (ƊG-ƊGR).
