变形量对(CoNiV)97Al3中熵合金组织和力学性能的影响OA
Effect of deformation on microstructure and mechanical properties of(CoNiV)97Al3 medium entropy alloy
高强度和高塑性的中熵合金,相较于传统合金能够满足更多的实际应用.通过在CoNiV合金中掺入微量Al,经过退火处理来提高其力学性能.制备了不同Al含量的铸态(CoNiV)100-xAlx(x为 1、2、3、4、5,原子分数/%)合金.采用万能试验机、维氏硬度计、X射线衍射仪、光学显微镜、扫描电子显微镜、透射电子显微镜,研究了退火温度、Al含量及拉伸变形量对合金力学性能、显微组织的影响.实验结果表明,随着Al含量的增加,合金的伸长率提升到 30%以上…查看全部>>
Compared with traditional alloys,medium entropy alloys with excellent properties such as high strength and high plasticity can satisfy more practical applications.In this paper,the mechanical properties of CoNiV alloy were improved by adding small amounts of Al into the alloy and annealing at different temperatures.As-cast(CoNiV)100-xAlx(x=1,2,3,4,5 atom fraction/%)alloys with different Al content were prepared.Using a universal testing machine,Vickers hardn…查看全部>>
