研究ZL107铝合金经过固溶和时效处理后的Si相形态演化及其对力学性能的影响.结果表明,当合金在560℃固溶处理6h后,有部分Si相固溶进入基体,但在随后的时效过程中Si相会重新析出.比较了变质和未变质ZL107合金的固溶时效过程.通过La变质处理再固溶时效,ZL107合金中的Si相形态明显细化,合金的力学性能提高幅度更大.
研究ZL107鋁閤金經過固溶和時效處理後的Si相形態縯化及其對力學性能的影響.結果錶明,噹閤金在560℃固溶處理6h後,有部分Si相固溶進入基體,但在隨後的時效過程中Si相會重新析齣.比較瞭變質和未變質ZL107閤金的固溶時效過程.通過La變質處理再固溶時效,ZL107閤金中的Si相形態明顯細化,閤金的力學性能提高幅度更大.

The phase morphology evolution during the solid solution treatment and then artificial aging of the La-modified ZL 107 Al alloy was studied.The results show that when the solid solution was held at 560 ℃ for 6 h,only partial Si phase dissolved into the matrix; however,the precipitation also occurred during the artificial aging process.The precipitation process in Al-Si alloys with or without La-modification was compared.After modification and heat treatment,the mechanical properties of the alloy were greatly enhanced,due to the modification and uniform distribution of Si phase.
