The constrained phase transformation of prestrained TiNi fibers embedded in metal matrix smart composite

The reverse martensitic transformation of TiNi fibers embedded in a metal matrix smart composite has been studied. Results show that under the influence of temperature and recovery stress, the reverse martensitic transformation of TiNi fibers can be divided into two parts with different kinetic characteristics: the reverse transformation of self-accommodating martensite and that of oriented martensite. The relationship between martensitic fraction and temperature was calculated. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
