研究了提高熔体喷射温度和附加高温（１２００℃）处理对快凝Ａｌ－（１４％－１８％）Ｓｉ合金条带微观组织结构、硬度及韧性的影响，分析了因不同处理温度而引起的熔体结构变化对快凝微观组织的影响规律的冶金物理本质，实验发现，快凝熔体喷射温度的提高或在熔体喷射前附加高温（如１２００℃）或恒温均匀化处理，有利于合金微观组织均匀化和细化，有利于快凝条带综合机械性能的优化．
The effects of increasing the melt spraying temperature and the additional high temperature (1200 ℃) on the microstructure, hardness and toughness of the rapidly solidified Al- (14% -18%) Si alloy strip were studied. The effects of different treatment temperatures The experimental results show that the increase of the jetting temperature of the fast-melt melt or the additional high temperature (such as 1200 ℃) or the uniform temperature before melt-jetting are beneficial to the metallurgical properties of the alloy Homogenization and refinement of the microstructure are conducive to the optimization of the comprehensive mechanical properties of the strip.
