| Abstract: | A specimen current heating dynamic sintering process was developed to manufacture metal matrix composite. The corresponding equipment was built up. The properties of the 10v% SiCp/Fe composites made by the dynamic sintering and powder metallurgy were compared. The properties and the microstructures of the composites in current sintering with different dies were studied and the sintering mechanisms were analyzed. The results show that properties of composites can be improved significantly by the specimen current heating dynamic sintering when ceramic die is used and microstructure is homogeneous and refined. |
