摘　　要：通过对比热等静压前后铝合金铸件的冶金质量和金相组织的变化,研究了热等静压对铝合金铸件冶金质量和组织致密度的影响。结果表明,铸件经热等静压处理后,可有效修复铸件中的显微缩孔及疏松缺陷,使铸件组织更加致密均匀,但对于严重的海绵状疏松及宏观疏松,热等静压无法使其愈合。By comparing the changes in metallurgical quality and microstructure of aluminum alloy castings before and after hot isostatic pressing,the effect of hot isostatic pressing on the metallurgical quality and microstructure density of the aluminum alloy castings was studied.The results showed that after hot isostatic pressing treatment,micro shrinkage and porosity defects in castings were effectively repaired,making the microstructure of castings more dense and uniform.However,for severe sponge like and macroscopic porosity,hot isostatic pressing could not heal them.
