摘要
以锥形高强铸造铝合金为对象,研究了高温蠕变行为对产品固溶后校形的影响。通过热处理模拟,得到了材料在高温下的应力-应变曲线,研究表明,锥形高强铸造铝合金在高温下表现出明显的蠕变现象。通过对蠕变数据的分析,建立了材料的蠕变本构模型,预测产品在实际应用中的变形情况。根据产品结构形式,设计了产品的蠕变工装,起到了在时效过程中,对产品进行校形的作用,缩短了生产周期,具有一定的工程应用价值。
This study focuses on conical high-strength cast aluminum alloy,investigating the influence of high-temperature creep behavior on post-solution heat treatment deformation.Through heat treatment simulation,stress-strain curves of the material at high temperatures were obtained,revealing significant creep phenomena in the conical high-strength cast aluminum alloy at elevated temperatures.By analyzing the creep data,a creep constitutive model for the material was established to predict the deformation of the product in practical applications.Based on the product's structural design,a creepfixture was developed,effectively correcting the product's shape during aging,thereby reducing the production cycle.This approach demonstrates certain engineering practical value.
