工业冷却处理EN AW−6082和6005合金，在300°C以上发生析出。整个冷却过程中的析出相是平衡β相。在冷却之后的加热环节，仍保持有相当的析出量。扫描加热与工业预热处理方式相同，期间β-Mg2Si 还是主要形成相。而6060合金的析出主要发生在300°C以下，并且在200°C以下还伴有β′-Mg2Si颗粒的形成。%Precipitation during the industrial cool down takes place predominantly above 300 °C in the EN AW−6082 and 6005 alloys. The phase precipitation throughout cooling is equilibriumβphase. A considerable capacity is retained after the cool down for further precipitation during a subsequent heating cycle. Theβ-Mg2Si is once again the predominant phase that forms during a scan heating cycle employed in exactly the same manner with the industrial billet preheating operation. The precipitation in the 6060 alloy, on the other hand, occurs predominantly below 300 °C with additionallyβ′-Mg2Si particles formed below 200 °C.
