不同类型陶瓷颗粒对铁基复合材料力学性能的影响
Effects of Different Types of Ceramic Particles on Mechanical Properties of Iron Matrix Composites
摘要
Abstract
A number of iron matrix composites reinforced by different types of ceramic particles (SiC, Cr3C2, TiC and Ti(C, N)) were prepared by an electric current heating dynamic hot press technique and the mechanical properties of the composites were studied. The contribution of load sharing of different types of ceramic particles was investigated by Eshelby equivalent inclusion approach in order to interpret the experimental results and to reveal the strengthening mechanisms. It was found by experiments that SiC reinforcing particles show the strongest effect on improving the strength of the iron matrix composite and Cr3C2 reinforcing particles are only inferior to SiC. It is shown that the strengthening mechanisms in 10％TiC/Fe and 10％Ti(C, N)/Fe composites chiefly rely on load sharing of the reinforcements, while the strengthening mechanisms in the other two composites rely not only on load sharing of the reinforcement but also on increasing matrix strength.关键词
