不同陶瓷颗粒增强铁基复合材料力学性能的研究
A study on mechanical properties of iron matrix composite reinforced by different types of ceramic particles
摘要
Abstract
Mechanical properties of iron matrix composites reinforced by different types of ceramic particles (SiC,Cr3C2, TiC and Ti (C, N)) prepared by the two- stage resistance sintering were studied experimentally. It was found that tensile strength of SiC/Fe composite shows the highest among the four types of composites. The elongation of all the composites decreases as increasing of reinforcement volume fraction. The stress - strain curves of the composites were simulated by Eshelby approach modeling to reveal the strengthening mechanisms. The modeling and microstructure observations suggest that the strengthening mechanism of the iron matrix composites relies not only on load sharing of the reinforcements but also on reinforcement increasing matrix strength.关键词
