At the time of deformation reached 40%, the appearance of the crystal changed greatly: the size refined, boundary turned clear, second phase disappeared and twin crystal structure appeared.
变形量为40%时，轧板的晶粒形貌发生了显著变化，晶粒变得细小，晶界清晰，第二相完全消失，并出现孪晶组织。
Structure analysis showed that the incoordination in deformation process of two phases is the main reason why microcrack occurs at phase boundary.
组织分析显示，两相之间变形不协调是相界微裂纹产生的根本原因。
