液态浸渗挤压al2o3sf/2a12铝基复合材料表面损伤的预测
Keywords: 复合材料,？液态浸渗挤压,？表面损伤,？有限元,？预测
Abstract:
？建立了al2o3sf/2a12铝基复合材料液态浸渗挤压表面缺陷预测的数学模型,基于l9(34)正交试验实验表模拟了9种在不同工艺参数下液态浸渗挤压成形al2o3sf/2a12铝基复合材料制件的损伤分布规律,研究了工艺参数对损伤形成的影响规律.结果表明:由于不均匀变形以及制件表面的局部过热,在坯料模角处易产生表面环向裂纹;保压时间对表面损伤形成的影响最大,其次为浇注温度和模具预热温度,挤压速度的影响比较小.通过优化工艺参数,可以有效地避免表面损伤的产生,挤出表面质量良好的制件,模拟结果与实验结果基本吻合.
