摘　　要：作为材料的基本性能之一,强度的预测对复合材料的设计、制备和应用等具有十分重要的指导作用。因此,综述屈服强度的强化机制,包括细晶强化、Orowan强化、热膨胀系数错配强化、载荷转移强化、加工硬化强化以及弹性模量错配强化,以期为颗粒增强金属基复合材料屈服强度的预测提供参考。Strength is one of the basic properties of material, the prediction of strength plays an important role in the design,preparation and application of composite materials. In this paper, based on the strengthen mechanisms, the researches on prediction models of particle-reinforced metal matrix composites including grain refinement strengthen, Orowan strengthen,thermal expansion coefficient misfit strengthening, load transfer strengthen, work hardening strengthen, and elastic modulus mismatch strengthen. This short review is expected to provide guidance for yield strength prediction of particle-reinforced metal matrix composites.
