摘要
对铸态Al-Mg-Si-Fe-RE新型铝合金试样分别进行了常规均匀化热处理和磁场均匀化热处理,并测试分析了试样低温力学性能和耐磨损性能。结果表明:磁场均匀化热处理较常规均匀化热处理更有利于提高试样的耐磨损性能和低温力学性能。与常规均匀化热处理相比,磁场均匀化热处理试样的抗拉强度、屈服强度、伸长率和冲击吸收功分别增大了59 MPa、52 MPa、8.4%、14.4 J,-40℃和25℃磨损体积分别减小了55.3%、56.8%。试样的均匀化热处理工艺优选为磁场热处理。
As-cast Al-Mg-Si-Fe-RE new-type aluminum alloy was heat treated by common homogenization heat treatment and magnetic field homogenization heat treatment,the mechanical property at low temperature and wear resistance of the alloy samples were tested and analyzed.The results show that magnetic field homogenization heat treatment is more conducive to improve the mechanical property at low temperature and wear resistance of the sample than common homogenization heat treatment.Comparing with the sample by common homogenization heat treatment,the tensile strength,yield strength,elongation and impact absorption energy of the sample by magnetic field homogenization heat treatment increases by 59 MPa,52 MPa,8.4%and 14.4 J,respectively,while the wear volume at-40℃and 25℃decreases by 55.3%and 56.8%,respectively.The optimized homogenization heat treatment process is magnetic field heat treatment.
