Abstract Most industrial alloys contain a matrix phase and dispersed second-phase particles. Several thermomechanical processing (TMP) steps are usually needed to produce a final product, during which recrystallization and its related phenomena may take place. Second-phase particles may retard or accelerate recrystallization, depending on their size and spatial distribution, the TMP conditions, among others. Besides their effect on recrystallization kinetics, the introduction of second-phase particles creates additional interfaces within the matrix, it also modifies the grain structure and crystallographic texture after recrystallization, which then either improves or deteriorates the associated mechanical properties of the investigated materials. The interactions between second-phase particles and recrystallization are further complicated when these particles are not stable. In addition to particle coarsening, they can also precipitate out or dissolve into the matrix before, simultaneously with or after recrystallization. This review article attempts to summarize the recent progresses on the complex interaction between second-phase particles and recrystallization and the science behind them. This double-edge effect of second-phase particles on recrystallization behaviour and mechanical properties of metallic materials is still far from being clear. A better understanding of this issue is of high academic and industrial interests, since it provides potential freedom for TMP design and microstructure control.

第二相粒子对金属材料再结晶行为及相关力学性能的双边效应

摘要 大多数工业合金含有基体相和分散的第二相颗粒。通常需要几个热机械加工 (TMP) 步骤来生产最终产品,在此期间可能会发生再结晶及其相关现象。第二相粒子可能会延迟或加速再结晶,这取决于它们的大小和空间分布、TMP 条件等。除了对再结晶动力学的影响外,第二相粒子的引入还会在基体中产生额外的界面,还会改变再结晶后的晶粒结构和晶体织构,从而改善或降低所研究材料的相关机械性能。当这些颗粒不稳定时,第二相颗粒和再结晶之间的相互作用会进一步复杂化。除了颗粒粗化之外,它们还可以在重结晶之前、同时或之后沉淀出或溶解到基体中。这篇综述文章试图总结第二相粒子与再结晶之间复杂相互作用的最新进展及其背后的科学。第二相粒子对金属材料再结晶行为和机械性能的这种双边效应仍远未明确。更好地理解这个问题具有很高的学术和工业利益,因为它为 TMP 设计和微观结构控制提供了潜在的自由。它们也可以在重结晶之前、同时或之后沉淀出或溶解到基体中。这篇综述文章试图总结第二相粒子与再结晶之间复杂相互作用的最新进展及其背后的科学。第二相粒子对金属材料再结晶行为和机械性能的这种双边效应仍远未明确。更好地理解这个问题具有很高的学术和工业利益,因为它为 TMP 设计和微观结构控制提供了潜在的自由。它们也可以在重结晶之前、同时或之后沉淀出或溶解到基体中。这篇综述文章试图总结第二相粒子与再结晶之间复杂相互作用的最新进展及其背后的科学。第二相粒子对金属材料再结晶行为和机械性能的这种双边效应仍远未明确。更好地理解这个问题具有很高的学术和工业利益,因为它为 TMP 设计和微观结构控制提供了潜在的自由。这篇综述文章试图总结第二相粒子与再结晶之间复杂相互作用的最新进展及其背后的科学。第二相颗粒对金属材料再结晶行为和机械性能的这种双边效应仍远未明确。更好地理解这个问题具有很高的学术和工业利益,因为它为 TMP 设计和微观结构控制提供了潜在的自由。这篇综述文章试图总结第二相粒子与再结晶之间复杂相互作用的最新进展及其背后的科学。第二相粒子对金属材料再结晶行为和机械性能的这种双边效应仍远未明确。更好地理解这个问题具有很高的学术和工业利益,因为它为 TMP 设计和微观结构控制提供了潜在的自由。
