The thermal behavior of two copper alloys, with 0.2 and 0.5 mass % of Mg, was analyzed after severe plastic deformation processing by Equal Channel Angular Pressing (ECAP). Both alloys were forced to be passed through a 90º inner angle ECAP die at room temperature up to 16 passes following route Bc. The thermal stability was analyzed in terms of the recrystallization kinetics by using the Various Heating Rates method, derived from the Johnson–Mehl–Avrami–Kolmogorov equation, after analyzing the Differential Scanning Calorimetry peaks for both alloys at any pass of ECAP. The calculated recrystallization parameters included the activation energies (E (kJ mol⁻¹) E_CuMg02 = 42.6 ± 19.8 E_CuMg05 = 52.7 ± 13 kJ mol⁻¹) and the kinetic exponent n which took an average value of ≈ 1.75, irrespective of the considered alloy.

在通过等通道角挤压（ECAP）进行了严重的塑性变形处理之后，分析了两种Mg为0.2和0.5质量％的铜合金的热行为。两种合金都必须在室温下通过90º内角ECAP模具，沿路径Bc最多可通过16次。在分析了任何ECAP通过后两种合金的差示扫描量热峰之后，通过使用从Johnson-Mehl-Avrami-Kolmogorov方程得出的多种加热速率方法，根据重结晶动力学分析了热稳定性。计算出的重结晶参数包括活化能（E（kJ mol ^-1）E _CuMg02  = 42.6±19.8 E _CuMg05  = 52.7±13 kJ mol^-1）和动力学指数n的平均值约为1.75，与所考虑的合金无关。
