CNT对5052铝合金体能训练器材组织和力学性能的影响

Effects of CNT on Microstructure and Mechanical Properties of 5052 Aluminum Alloy Rackets

为了提高体能训练器材的综合性能,提升训练器材在教学训练中的实用性,选择5052铝合金为基材,利用高能球磨方法实现碳纳米管(CNT)的良好分散,通过粉末冶金工艺制得复合材料,同时对其组织结构、强化作用机制与各向异性进行了分析。研究结果表明:加入不同CNT添加量的复合材料中形成了致密组织;提高CNT添加量后,复合材料达到了更高的拉伸强度,伸长率减小。该材质设计的训练器材在院校、专业队、部队等高强度体能训练环境中具有较高的稳定性和实用性。

In order to improve the comprehensive performance of physical training equipment and enhance the practical use of training equipment in teaching and training,5052 aluminum alloy was selected as the base material,and the carbon nanotube(CNT)was well dispersed by high energy ball milling method.The composite material was prepared by powder metallurgy process.At the same time,its structure,strengthen⁃ing mechanism and anisotropy were analyzed.The experimental results show that the dense tissue is formed in the samples with different amounts of CNTs.After increasing the amount of CNTs,the tensile strength of the samples is higher and the elongation decreases.The training equipment designed by the material has high stability and practicability in the high-intensity physical training environment such as colleges,profes⁃sional teams and troops.
