摘要
采用拉伸试验和埃里克森杯突试验研究了退火处理对Zr添加5182铝合金性能和表面质量的影响。研究结果表明:Zr添加5182铝合金较未添加Zr的合金表现出明显的优势。在370~450℃范围内,5182铝合金的强度、r和杯突值IE随温度的升高而减小,经450℃/2h退火处理后拉伸和杯突试样表面均出现橘皮组织,而在该温度区间时,5182+Zr铝合金性能随温度变化不明显,经450℃/2h退火处理后拉伸和杯突的试样表面质量良好。
Effect of annealing on properties and surface quality of5182aluminum alloy with Zr addition was investigated by tensile test and Erichsen cupping test.The results indicated that the alloy with Zr addition exhibited obvious advantages compared with the alloys without Zr.With temperature changing from370℃to450℃,the strength,coefficient of normal anisotropy and cupping test value of5182aluminum alloy decreased with temperature increasing.The alloy displayed tangerine hull constitution after annealed at450℃for2h.However,during this temperature range,the properties of5182aluminum alloy with Zr addition were not changed obviously as temperature increasing.Tensile test and Erichsen test showed that surface quality of the alloy was normal after annealed at450℃for2h.
