摘要
研究基于分子级混合及均质机均质的协同作用下,使用放电等离子体烧结工艺制备出石墨烯增强铜基复合材料,并设计试验探究不同热处理方法对复合材料热处理后对其力学性能的影响情况,由试验结果可知,热处理可以显著提高石墨烯增强新型建筑镁基复合材料的冲击性能、拉伸性能及致密度。其中水冷处理效果最优,空冷处理效果略差,而炉冷效果最差,经过水冷热处理后,材料的抗拉强度、屈服强度、断后伸长率、致密度和冲击性能提高了31.4%,39.5%,127.7%,59.93%和16.69%,表明水冷是优选的石墨烯增强新型建筑镁基复合材料热处理冷却方式。
Based on the synergistic effect of molecular-level mixing and homogenization by a homogenizer,this study used a discharge plasma sintering process to prepare graphene-reinforced copper-based composites,and designed experiments to investigate the effect of different heat treatment methods on the mechanical properties of the composite materials after heat treatment.The experimental results show that heat treatment can significantly improve the impact resistance,tensile properties,and density of the graphene-reinforced new type of building magnesium-based composite material.Among them,water cooling treatment has the best effect,air cooling treatment has a slightly worse effect,and furnace cooling has the worst effect.After water cooling heat treatment,the material's tensile strength,yield strength,elongation at break,density,and impact performance increased by 31.4%,39.5%,127.7%,59.93%,and16.69%,respectively,indicating that water cooling is the preferred heat treatment cooling method for graphene-reinforced new type of building magnesium-based composite materials.
