摘要 实验研究了CREM法半连铸7075铝合金过程中,低频交变电磁场对凝固前沿形态、微观组织结构、非平衡凝固液固相线位置、结晶区间间隔以及温度场和流动场的影响规律。并据此对CREM法抑制7075铝合金半连铸坯中溶质元素宏观偏析的机理进行了分析和说明。 In the producing process of 7075 aluminum alloy by CREM method, the effects of electromagnetic field with low frequency on the evolution of solidifying front shape, non-dendritic structure, liquidus and solidus temperature of non-equilibrium freezing, solidification interval, flow pattern and temperature field have been experimentally investigated. An explanation is also given to the mechanism of CREM process on restraining macro-segregation of solute elements in 7075 aluminum alloy ingot by DC cast.
