摘要/Abstract

摘要：

研究了用放电等离子体烧结(SPS)方法制备了不同含量(1vol%、3vol%、5vol%、7vol%)的多壁碳纳米管(MWNTs)强韧化Fe₃Al金属间化合物基复合材料的力学性能和微观结构. 用X射线衍射和TEM、SEM测定其物相组成和显微结构, 利用万能材料试验机对其力学性能进行测试, 并对其强韧化机制进行分析. 研究表明, 多壁碳纳米管在烧结过程中被完整保存下来; 在MWNTs含量为3vol%时, 复合材料的室温断裂韧性和压缩屈服强度分别为40 MPa·m^1/2、3175 MPa. 复合材料强韧化的主要机制是碳纳米管的拔出和桥联.

Abstract:

Novel Fe₃Al composites strengthened and toughened by 1vol%, 3vol%, 5vol% and 7vol% multi-walled carbon nanotubes (MWNTs) were fabricated by spark plasma sintering (SPS). X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were carried out to determine the phase composition, and to analyze the microstructure and crack propagation of the composites. Fracture toughness and compressive yield strength were determined at room temperature. Then, the strengthening and toughening mechanism of MWNTs in the composites were discussed. Experimental results show MWNTs keep perfect structure intact in the composite. The fracture toughness and compressive yield strength of composite with 3vol% MWNTs reach the maximum values of 40 MPa·m^1/2 and 3175 MPa, respectively. The bridging effect on cracks and pullout of MWNTs are possible strengthening and toughening mechanisms.

Key words: Fe₃Al composite, strengthening and toughening, mechanical property
