摘要 由于凝固过程的枝晶生长和元素偏析等行为,双相高熵合金很难获得良好的综合力学性能。不同于设计共晶高熵合金或改善铸造工艺,借助亚稳态相变可以调控高熵合金的微观组织和力学性能。多主元高熵合金物相组成和分布与组元种类和含量密切相关,固态相变对合金组织和性能的影响规律不尽相同。采用真空电弧熔炼制备AlCoCrFeNix(1.4≤x≤1.7)高熵合金,研究高温热处理过程合金微观组织的演变及其对力学性能的影响。结果表明,随Ni含量增加,铸态高熵合金BCC/B2枝晶组织比例逐渐降低,晶间区域比例逐渐增加,且由FCC单相组织转变为共晶组织。合金屈服强度和抗拉强度分别由1 067 MPa(x=1.4)和1 416 MPa(x=1.5)降低至464 MPa和1 191 MPa(x=1.7),延伸率由1.7%(x=1.4)提升至11.5%(x=1.7)。经1 100 ℃高温热处理,BCC/B2枝晶组织转变为FCC和B2双相组织,合金强度均有所降低,塑性明显提升。热处理态AlCoCrFeNi1.6和AlCoCrFeNi1.7高熵合金呈现典型的两级网状组织,且因FCC相脱溶析出B2相,合金屈服强度降幅逐渐减小。其中,热处理态AlCoCrFeNi1.7高熵合金屈服强度和抗拉强度降幅分别仅为4.1%和7.5%,而延伸率增幅达52.2%,综合力学性能显著提升。

Abstract: Due to dendrite growth and element segregation during solidification, dual-phase high-entropy alloys cannot possess good comprehensive mechanical properties. Different from the design of eutectic alloy and the modification of casting process, phase transition of the metastable phase provides an optional route to regulate the microstructure and mechanical properties of the high-entropy alloy. However, phase constitution and distribution are closely related to the type and content of the alloying element, resulting in the varying effect of the solid-state phase transformation on the microstructure and mechanical properties of the multi-component high-entropy alloys. AlCoCrFeNix (1.4≤x≤1.7) high-entropy alloys were prepared by arc-melting method and the effect of high-temperature heat treatment on the microstructure and mechanical properties was investigated. As the Ni content is increased, the proportion of dendrite region (BCC/B2 spinodal structure) decreases gradually, while the proportion of interdendrite region increases with the structure evolving from FCC dendrite to FCC/B2 eutectic. Correspondingly, the yield strength and tensile strength of the alloys decrease from 1 067 MPa (x=1.4) and 1 416 MPa (x=1.5) to 464 MPa and 1 191 MPa (x=1.7), respectively, and the elongation increases from 1.7% (x=1.4) to 11.5% (x=1.7). After heat treatment at 1 100 ℃, the BCC/B2 spinodal structure transforms into FCC and B2 dual-phase structure, giving rise to the increase of plasticity and the decrease of strength. The heat-treated AlCoCrFeNi1.6 and AlCoCrFeNi1.7 high-entropy alloys present the typical network structure of the FCC phase, which contains the B2 precipitates and can prevent the reduction of the yield strength. The heat-treated AlCoCrFeNi1.7 high-entropy alloys possess the good comprehensive mechanical properties with 52.2% increment in elongation, while the decrement in yield strength and tensile strength are only 4.1% and 7.5%, respectively.
