锌基合金塑性成形的研究

Research on the Plasticity Form of Zinc-Based Alloys

锌基合金（ＺＡ２２，ＺＡ２７）可以挤压和轧制成形，但挤压成形塑性偏低。通过固溶后自然时效处理，可有效地提高合金的综合力学性能；挤压后直接人工时效，可有效地提高合金的塑性。

Zinc-based alloys(ZA22,ZA27) may be formed by rolling and extrusion but with lower plasticity after extruding.The results indicate that natural ageing after solution heat-treatment leads to the effective increasement of the comprehensive mechnical properties.Moreover,after extruding the alloys can improve their plasticity if artificial ageing is processed.
