【摘要】 基于Fe-Ni包晶合金,Fe-B共晶合金和Ni基高温合金在快速凝固条件下的液/固相变过程对随后固态相变的影响规律,综合论述了非平衡凝固抑制包晶反应决定δ/γ转变路径,控制亚稳/稳态相转变和细化沉淀相等作用.结合相关理论分析了非平衡凝固过程与固态相变的内在物理联系.上述研究体现出进行非平衡凝固与固态转变一体化研究的科学意义.更多还原

【Abstract】 Based on Fe-Ni peritectic alloy,Fe-B eutectic alloy and Ni multi-component superalloy,the influence of non-equilibrium solidification on subsequent solid-state transitions has been reviewed,and the physical relation of the two transformations has been discussed.The transformation behavior includes non-equilibrium solidification,peritectic reaction,δ/γ transformation,metastable-stable transformation,and precipitation.On this basis,it is proposed to carry out a united analysis for non-equilibrium solidification and solid-state transformation.更多还原
