| Abstract: | The effects of Ni-coated SiC powder on the mechanical properties and fracture mechanism of the SiCp/Fe composites have been studied. The results show that the strength, toughness and hardness of the composites with the coated SiCp/Fe are greatly increased in comparison with the composites with uncoated SiCp/Fe. The reason is believed to be the improved interfacial bonding. |
