摘要
通过不同的热处理工艺改变原位TiCp/Fe复合材料的基体组织 ,探讨了原位TiCp/Fe复合材料不同基体组织与性能的关系。试验结果表明 :在热处理过程中基体组织明显改变 ,TiC增强相不发生变化。退火处理降低材料的硬度 ,提高材料的韧性。淬火 +低温回火处理使材料的强度和硬度提高 ,而韧性没有明显的下降。采用等温淬火工艺 ,可使TiCp/Fe复合材料具有最好的综合力学性能。
The matrix microstructure of TiC p/Fe composites was changed under different heat treatment processes. The relations between different matrix microstructures and properties were discussed. The results show that the particulates of TiC have no change in heat treatment, but the matrix microstructure has changed in the same situation. When the composite being annealed, the hardness of composite can be lowered and the toughness of composite can be improved. The quenching+tempering at low temperature could enhance the strength and hardness with few decrease of toughness. After isothermal quenching, TiC p/Fe composites possess the best mechanical properties.
