摘要
通过对断裂模具的化学成分、显微组织及裂纹形态进行分析观察,确认模具是由于热处理工艺不当,在工作过程中产生疲劳裂纹而导致断裂。
Through the analysis and observation of the chemical composition, microstructure and the ruptured shape for the ruptured dies, it is confirmed that the rupture of the dies was caused by the improper heat treatment process and the fatigue cracks during the operation.
