Abstract

Abstract

En 中文
• The evolution of twinning-induced SRX in pre-twinned Mg-Y-RE alloys during high-temperature annealing was systematically analyzed. • Static recrystallization induced by {10–12} and {11–21} extension twins was observed. • The thermal restoration mechanism of Mg-Y-RE alloys was revealed through machine learning. • The Grad-CAM visualization technique illustrates the correlation between input microstructural images and the output, the resulting visual heatmap accurately identifies key regions where recrystallization nucleation occurs.
