In this study, we used Crofer 22 H stainless steel to observe the microstructure after deformation and annealing in a bcc structure. By the invisibility criteria of transmission electron microscope (TEM), it is possible to analyze the slip system with ECCI taken at different g vectors. By comparing ECCI after different steps of annealing, we observed the evolution of dislocation structure and the precipitation. Jui-Chao Kuo 郭瑞昭 2017 學位論文 ; thesis 73 zh-TW
