Research of Productive Process of Section Extrusion for AZ31 Magnesium Alloy

摘要

The productive process of the section extrusion for AZ31 magnesium alloy has been researched on the productive line by device of horizontal extrusion. The best extrusion operation is designed for AZ31 magnesium alloy. For example: the temperature of the extrusion barrel, the temperature of Mg billets, the preheating temperature of the die, the extrusion speed and the technique of the designed die and the process by which fine crystal granularity can be obtained. The results show that the highest yield strength and tensile strength are obtained and the section extrusion has better plasticity, fine crystal granularity and glabrous surface by analysis of the rnicrostructure and mechanical properties of the section extrusion.
