摘要/Abstract

摘要： 采用挤压铸造和功率超声耦合的方式处理Al-5.0Cu合金熔体,利用光学显微镜观察不同工艺参数下的Al-5.0Cu合金的微观组织。使用反分析法计算出耦合作用下铸件-模具的界面换热系数曲线,在此基础上结合CAFE宏-微观耦合模型模拟出不同工艺下Al-5.0Cu合金的凝固组织,并与宏观腐蚀结果进行对比,试验同时测量了熔体内部不同位置的温度变化。通过数值模拟和试验验证相结合的方式,对比研究了不同工艺对Al-5.0Cu合金凝固组织的影响。模拟和试验结果均表明,功率超声和挤压铸造的耦合作用较于单一外场作用能进一步改善合金的凝固组织,同时可以完全消除铸造缺陷;耦合作用还可以使得熔体内部温度分布更加均匀,显著细化Al-5.0Cu合金的初生晶粒,有利于得到均匀、细小微观组织。该结果为细化Al-5.0Cu合金的组织,提高合金的力学性能提供了新的思路。

Abstract: The Al-5.0Cu alloy melt is processed by combined fields of squeeze casting and ultrasonic vibration, and the microstructure under different process parameters are examined by OM. The interfacial heat transfer coefficient curve between cast and mold under combined fields is calculated using inverse analysis, then the solidification microstructures under different conditions are simulated based on CAFE model and compared with the macrostructure, the temperature change during the experiment in the melt is also measured. The effects of different processes on the solidification structure of Al-5.0Cu alloy were studied by means of numerical simulation and experimental verification. The results show that combined fields can further improve the solidification structure of the alloy and completely eliminate the casting defects compared with the single external field. The combined fields can also lead to the uniformly distribution of temperature in the melt and significant refinement of Al-5.0Cu alloy primary grain, which is beneficial to obtain uniform and fine microstructure. The results provide a new idea for refining the microstructure and improving the mechanical properties of Al-5. 0Cu alloy.
