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

Keywords： kinetic equation

The apparent activation energies and frequency factors of the double reversible transformations occurring in heating CuZnAlMnNi shape memory alloy (SMA) were deduced as AEx .M = 62.597 8 kJ/mol, AEm.A 153.92 kJ'mol,Ax-m = 5.223 2 × 109s 1, and AM-A = 2.325 1 × l023 s 1, respectively. The kinetic equations of the two transfornations during heating were established simultaneously.
