7050铝合金在不同温度变形的动态析出行为
Keywords: 金属材料,7050铝合金,热变形,动态析出,mgzn2相
Abstract:
？通过gleeble-1500模拟试验机上模拟热变形实验，研究7050铝合金在不同变形温度时mgzn2相动态析出过程。研究结果表明：mgzn2相动态析出不会对流变应力的波动产生影响，变形加速动态析出过程。随着变形温度的升高，部分析出相mgzn2颗粒由球状变成板条状，尺寸增大数量减少，粗大的板条状mgzn2相在450℃变形过程中易破碎；同时位错密度减低，位错胞团变成离散位错墙。析出相钉扎位错和阻碍晶界迁移，主要以亚稳态η′和平衡态η形式存在，在变形过程中不会产生微裂纹。
