陶瓷颗粒增强粉末冶金Fe–2Cu–0.6C复合材料的微观结构和力学性能
|
摘要
采用传统粉末冶金压制/烧结技术,经600 MPa压制、1140℃烧结制备了陶瓷颗粒增强(SiC、TiC及TiB_2陶瓷颗粒,质量分数0～1.6%)Fe–2Cu–0.6C低合金钢复合材料,对三种复合材料的微观结构和力学性能进行了研究。结果表明:在烧结过程中,SiC与TiB_2颗粒与基体发生反应,故而与基体界面结合良好;当添加质量分数为1.6%的SiC颗粒时,复合材料烧结后的布氏硬度与抗拉强度分别比基体提高了35.9%、69.4%;添加质量分数为1.2%的TiB_2颗粒时,复合材料相对密度比基体提高了5.3%,其烧结硬度、抗拉强度与基体相比分别提高了77.9%、72.6%;由于烧结过程中TiC颗粒不与基体发生反应,故而添加TiC颗粒对复合材料的布氏硬度、抗拉强度影响不大。
Ceramic particle-reinforced Fe–2 Cu–0.6 C low-alloy steel composites(SiC, TiC, and TiB_2 ceramic particles in the mass fraction of 0～1.6%) were prepared by the conventional powder pressing/sintering technology at 600 MPa and 1140 ℃, the microstructures and mechanical properties of composites were investigated. The results show a good interface bonding between the reinforced particles(SiC and TiB_2) and the matrix because of the reaction during sintering. The Brinell hardness and tensile strength of the sintered composites added with 1.6% SiC particles by mass increase by 35.9% and 69.4%, respectively, compared with those of Fe–2Cu–0.6C matrix. When 1.2% TiB_2 particles by mass are introduced, the hardness and tensile strength of the sintered composites increase by 77.9% and 72.6%, respectively, compared with those of the matrix. Meanwhile, it is noted that the relative density of the TiB_2-reinforced low-alloy steel composite also increases by 5.3%. The addition of TiC particles has little effect on the Brinell hardness and tensile strength of the composites due to no reaction between TiC particles and the matrix.
