Abstract

Commercial purity aluminum was reinforced with different percentages of carbon nanohorns (CNH) using ball milling (1 h) followed by spark plasma sintering (SPS) at 550 °C for 5 min under 50 MPa pressure with heating rate 100 °C/min. The microstructure, hardness and compression properties of the spark-plasma-sintered carbon-nanohorns-reinforced aluminum (Al-CNH) composites were evaluated. Transmission electron microscopy revealed a uniform distribution of 0.3% CNH in Al, but above 0.3% CNH, agglomeration occurred. The compression strength of Al-0.3%CNH composites increased by 44% compared to the milled Al sample without CNH.

球磨-等离子烧结制备碳纳米角增强铝复合材料的组织和力学性能

摘要

使用球磨（1 h），然后在550°C，50 MPa压力，550 MPa压力，加热速率100°C / min的条件下，进行5分钟的火花等离子体烧结（SPS），以不同百分比的碳纳米角（CNH）增强商业纯度的铝。评价了电火花等离子体烧结碳纳米角增强铝（Al-CNH）复合材料的微观结构，硬度和压缩性能。透射电子显微镜显示在Al中0.3％的CNH均匀分布，但是在0.3％CNH以上时，发生团聚。Al-0.3％CNH复合材料的压缩强度与不带CNH的研磨Al样品相比增加了44％。
