摘要
Precipitation during the industrial cool down takes place predominantly above 300 degrees C in the EN AW-6082 and 6005 alloys. The phase precipitation throughout cooling is equilibrium beta phase. A considerable capacity is retained after the cool down for further precipitation during a subsequent heating cycle. The beta-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 degrees C with additionally beta'-Mg2Si particles formed below 200 degrees C.
