摘要
针对高性能压力铸造AC4B铝合金的开发,在其标准成分范围内设计正交试验方案,应用热力学计算软件研究合金的机械性能和热力学性能.仿真结果显示,合金成分元素对其机械性能的影响次序为:Cu＞Fe＞Si＞Mg＞Mn＞Zn＞Ni,获得了最优的合金成分组合,并讨论了正交试验设计方法的局限.最后对两组高性能合金的析出相进行热力学计算,并分析了析出相含量对其机械性能的影响.
Abstract
For the development of aluminum alloy AC4B for high-performance pressure die-casting,an orthogonal experi-mental design is conducted within the standard composition range.Thermodynamic calculation software is applied to study the alloy's mechanical and thermodynamic properties.The simulation results indicate that the order of influence of alloy composition elements on mechanical properties is:Cu＞Fe＞Si＞Mg＞Mn＞Zn＞Ni.The optimal combination of alloy composition is obtained,and the limitations of the orthogonal experimental design method are discussed.Lastly,ther-modynamic calculations are performed on the precipitate phases of two high-performance alloys,and the effects of precipi-tate phase content on their mechanical properties are analyzed.
