【摘要】 分析了铸造合金颗粒复合材料中增强相（ＳｉＣ颗粒）与基体（铸铁）界面结合的形态及影响因素、界面结合机制和稳定性，提出了改善界面结合状态的方法．在实验室条件下，采用离心铸造工艺制取铁基／ＳｉＣ颗粒复合材料，通过金相分析和电子探针等测试手段．研究了经不同的高温处理后铁基／ＳｉＣ颗粒复合材料界面变化规律．更多还原

【Abstract】 The interface behaviour and stability of iron-based composites containing SiC particles incorporated by the centritugal casting technique was investigated in this paper. With different heating temperaturesand prologation time, the combination of the interface between the sic particles and the matrix in high temporature was tested by SEM. It is explained by the basic theory of metal diffusion.更多还原
