Abstract:增材制造根据热源不同,分为激光增材制造、电子束增材制造、搅拌摩擦增材制造等,在热源作用下微观结构的演化对增材制造构件的力学性能具有重要影响,因此,有必要发展在不同热源体系下微观结构中材料的凝固、相变等的演化。针对激光热源,分别采用Monte Carlo法和相场法模拟熔池中材料的凝固,将激光热源的移动速度和熔池温度梯度与晶粒生长模型相结合,并通过与试验的对比,验证了材料凝固模型的正确性。针对具有固态相变的材料,如Ti-6Al-4V,进一步发展了两尺度MonteCarlo模型,分别模拟在激光热源作用下的?相的凝固和?相的生成。对搅拌摩擦增材制造,采用红外测温仪进行温度测试,并用Keller试剂腐蚀后的晶粒结构验证了所建立的铝合金搅拌摩擦增材制造Monte Carlo模型的正确性,并进一步结合铝合金析出相演化对力学性能进行了计算和验证。
