颗粒增强低成本钛基复合材料

Study on Particulate-reinforced Titanium Matrix Composite with Low Cost

摘要:

采用TiC颗粒和熔铸法制备TiCp／TIMETAL62S复合材料，研究了钛基复合材料的显微组织和室温力学性能。结果表明：TiCp／TIMETAL62S复合材料的组织由针状αa相、少量β相和TiC颗粒组成；TiC颗粒改变了基体合金原有组织，促进了复合材料组织的细化；钛基复合材料具有良好的室温强度和塑性，复合效果良好。

Abstract:

The microstructure and room-temperature mechanical properties of TiC-particulate-reinforced TIMETAL 62S matrix composite produced by melting process have been investigated. It shows that the structure of TiC p/TIMETAL 62S consists of acicular alpha phase, little amount of beta phase and TiC particles; TiC particles can change matrix structure, and promote composite structure fine; this composite has good strength and ductility at room temperature, and good comprehensive effect.
