Kinetic equations characterizing double reversible transformations in heating CuZnAlMnNi shape memory alloy

摘要

The apparent activation energies and frequency factors of the double reversible transformations occurring in heating CuZnAlMnNi shape memory alloy (SMA) were deduced as △EX-M = 62.597 8 kJ/mol, △EM-A= 153.92 kJ/mol, AX-M= 5.2232 ×109s-1 , and AM-A 2.325 1×1023s-1, respectively. The kinetic equations of the two transformations during heating were established simultaneously.
