Abstract The kinetics of Cr clustering process in a commercial Cu-1Cr-0.1 Zr (wt.%) alloy processed by equal channel angular pressing (ECAP) via route BC at room temperature for 1, 8 and 16 passes, has been investigated using Differential Scanning Calorimetry (DSC). The DSC scan results showed that the Cr clustering peak temperature reaction increases with increasing the heating rate and decreased with the imposed strain. The activation energy of clustering was estimated using Kissinger, Boswell and Ligero analytical methods. The obtained values were in the range of ∼137 and 144 kJ/mol. The Avrami parameter n was around unity which corresponds to a process of grain boundary nucleation after site saturation.

等通道角挤压加工的 Cu-Cr-Zr 合金中 Cr 团簇的动力学：DSC 研究

摘要 在室温下通过路线 BC 等通道角挤压 (ECAP) 加工 1、8 和 16 道次的商用 Cu-1Cr-0.1 Zr (wt.%) 合金中的 Cr 团簇过程动力学已使用微分法进行了研究。扫描量热法 (DSC)。DSC扫描结果表明，Cr团簇峰温度反应随着加热速率的增加而增加，随着施加应变而降低。使用 Kissinger、Boswell 和 Ligero 分析方法估计了聚类的激活能。获得的值在~137和144 kJ / mol的范围内。Avrami 参数 n 大约为 1，这对应于位点饱和后晶界成核的过程。
