Four strengthening mechanisms of Cu-rich nanoprecipitate-strengthened steel were summarized, including solid solution strengthening, grain boundary strengthening, dislocation strengthening and precipitation strengthening. The evaluation methods for various strengthening mechanisms were thoroughly elaborated based on the characteristics of both matrix and nanoprecipitates. The results showed that all kinds of strengthening mechanisms were closely related to the interaction with dislocations, and different strengthening mechanisms were coupled with each other in the microstructure. This provided theoretical support for the design of noval Cu-rich nanoprecipitate-strengthened steels.

概述了富铜纳米相强化钢的四种强化机制即固溶强化、晶界强化、位错强化和沉淀强化，并说明了各种强化机制的评估方法以及强度计算方式，结果表明各种强化机制均与位错的相互作用密切相关，不同强化机制在微观结构中相互耦合，为设计和制备高强度富铜纳米相强化钢提供了理论支持。

概述了富铜纳米相强化钢的四种强化机制即固溶强化、晶界强化、位错强化和沉淀强化，并说明了各种强化机制的评估方法以及强度计算方式，结果表明各种强化机制均与位错的相互作用密切相关，不同强化机制在微观结构中相互耦合，为设计和制备高强度富铜纳米相强化钢提供了理论支持。

富铜纳米相强化钢  /  固溶强化  /  晶界强化  /  位错强化  /  沉淀强化

Four strengthening mechanisms of Cu-rich nanoprecipitate-strengthened steel were summarized, including solid solution strengthening, grain boundary strengthening, dislocation strengthening and precipitation strengthening. The evaluation methods for various strengthening mechanisms were thoroughly elaborated based on the characteristics of both matrix and nanoprecipitates. The results showed that all kinds of strengthening mechanisms were closely related to the interaction with dislocations, and different strengthening mechanisms were coupled with each other in the microstructure. This provided theoretical support for the design of noval Cu-rich nanoprecipitate-strengthened steels.
