摘要
通过热挤压工艺对ZK60镁合金进行变形,研究了挤压比和挤压温度对T6态ZK60合金的显微组织和力学性能的影响。结果表明:挤压可以显著细化ZK60合金显微组织,并且挤压比越大,晶粒尺寸越细小,力学性能也得到较大提高;在试验中发现,在较低温度300℃时挤压所得到的ZK60镁合金组织均匀,力学性能较为良好。
The hot extrusion process was adopted to carry on the forming of ZK60 magnesium alloy, the effect of extrusion ratios and test temperatures on the microstructure and mechanical properties of ZK60 alloy under T6 condition was studied. The results show that the microstructure of ZK60 alloy is effectively refined after hot extrusion; the grains become finer and the tensile strength of the extruded ZK60 alloy gets obviously enhanced with increase of extrusion ratio. In this experiment, the ZK60 magnesium alloy at lower temperature 300℃ can gain homogeneous microstructure and good mechanical properties.
