本文介绍了金相检验技术在金属壳石英晶体振荡器真空冷压焊工艺试验中的一些应用实例。着重讨论了冷压焊焊缝和覆铜可伐带层间结合处的显微结构特征,建立了判别覆铜可伐带层间结合质量、冷压焊缝质量的粗略标准。同时也介绍了它在覆铜可伐带坯料退火温度的确定及覆铜层晶粒尺度测量中的应用。
This paper introduces some application examples of metallographic inspection technology in the vacuum cold welding process of metal shell quartz crystal oscillator. The microstructural features of joints between cold-pressed weld and copper-clad fava layer are discussed emphatically. A rough standard to judge the bonding quality between clad fissures and the quality of cold-pressed weld is established. At the same time, it also introduces its application in the determination of the annealing temperature of copper clad cutting billet and the grain size measurement of copper clad layer.
