非平衡凝固与固态相变的一体化研究

Considering both phase transition and material hot-working or material design, unified analysis of non-equilibrium solidification and solid-state phase transformations has profound significance of science and great prospect of engineering application. Here, non-equilibrium solidification and solid state transformation behavior, correlated with peritectic reaction, massive transformation, metastablestable transformation, precipitation, recrystallization and grain growth, for single phase solid solution alloy, eutectic alloy, peritectic alloy, multi-component super alloy and aluminum alloy, have been systematically reviewed. Regarding further the influence of non-equilibrium solidification on subsequent solid-state transformations, the new transformation mechanism induced by non-equilibrium solidification and the integrated microstructure regulation, the physical correlation between non-equilibrium solidification and subsequent solid-state transformations were discussed, and eventually, the microstructure control under the joint action of non-equilibrium solidification and solid phase transformations was realized. This review is expected to provide theoretical support for quantitative characterization of non-equilibrium solidification effect and microstructure prediction under the joint action of non-equilibrium solidification and solid-state transformations.
