摘要
通过放电等离子烧结(SPS)制备了CoCrFeMnNi/6061Al复合材料,采用SEM、XRD和纳米压痕等手段对其界面形貌和微区力学性能进行分析。结果表明,基体和增强颗粒间形成了厚度约为20μm的反应界面层,并生成了BCC固溶体相;复合材料微区的弹性模量和硬度变化趋势相同;界面层上的微纳力学性能高于基体和增强颗粒,界面层对复合材料力学性能的提高起重要的作用。
CoCrFeMnNi/6061 Al composites were prepared by spark plasma sintering. SEM, XRD and nanoindentation were used to analyze the interface morphology and microscale mechanical properties. The results show that the reaction interfacial layer with a thickness of about 20 μm is formed between the matrix and the reinforced particles, and BCC solid solution phase is generated. The change trend of elastic modulus and hardness in microscale is the same. The micro-nano mechanical properties of the interfacial layer are higher than those of the matrix and the reinforced particles. The interfacial layer plays an important role in improving the mechanical properties of the composites.
