摘要：

A calorimetric investigation of a commercial NiTi alloy of composition nearly 50:50 at.% with one- and with two-way memory effect is presented. The different training processes, used to obtain the two-way memory effect, generate some modifications such as a shift of the temperatures of transformation. The changes in the temperature and enthalpy of transformation between the one-way and two-way memory samples are presented, compared and discussed. These changes are believed to be explained by modifications in the free energy and energy level of the trained sample. (C) 1999 Elsevier Science B.V. All rights reserved.
