研究了Ti元素对CoCrFeNiMn高熵合金组织和性能的影响。采用真空电弧熔炼法制备了Ti元素变质的CoCrFeNiMnTix高熵合金。在CoCrFeNiMnTi0.25和CoCrFeNiMnTi0.55中观察到富含Ti的体心立方结构相,而不是CoCrFeNiMn中的简单面心立方结构。随着Ti含量的增加,富Ti相的量呈现出增加的趋势。同时,CoCrFeNiMnTix合金的力学性能也得到了明显的提高。当Ti含量为0、0.25和0.55时,显微硬度分别为175 HV、253 HV和646 HV,有明显的增加趋势,而塑性下降。拉伸性能表现出先增强后降低的趋势,从461 MPa到631 MPa再到287 MPa。当x = 0.55时,合金的固液转变温度降低,熔化温度范围增大。
The aim of this study was to investigate the effects of the Ti element addition on the microstructure and properties of CoCrFeNiMn high entropy alloys. The Ti element modified CoCrFeNiMnTix high entropy alloys were prepared by vacuum arc melting processing. The Ti rich body-centered cubic structure phase was observed in CoCrFeNiMnTi0.25 and CoCrFeNiMnTi0.55 instead of a simple face-centered cubic structure in CoCrFeNiMn. The amount of the Ti-rich phase depicted an increasing trend with increasing Ti content. Simultaneously, the mechanical properties of CoCrFeNiMnTix were obviously improved. When the Ti content is 0, 0.25 and 0.55, the microhardness is 175 HV, 253 HV and 646 HV, which has an obvious increasing trend, while the ductility decreased. The tensile properties show a trend of first strengthening and then decreasing, changing from 461 MPa to 631 MPa and then to 287 MPa. When x was 0.55, the solid–liquid transition temperature of the alloy decreased, and the melting temperature range increased.
