摘要/Abstract

摘要： 利用真空电弧熔炼制备了一种低密度Nb₃₇Ti₂₀Al₁₅Zr₁₅Hf₅Ta₅Mo₂W₁(at%)难熔高熵合金,并对该合金进行热变形和均匀化及750 ℃时效30~120 h。通过X射线衍射、扫描电镜、透射电镜、万能力学试验机等测试方法,对难熔高熵合金的铸态结构、时效后的析出行为和力学性能进行研究。结果表明,铸态难熔高熵合金结构为B2相基体+反相畴界。时效后,大量蠕虫状Zr₅Al₃相在晶内析出,晶界处有棒状Zr₅Al₃相析出,诱发晶间断裂。在30 h时效后,该合金的压缩屈服强度为1093.8±7.5 MPa。由于晶间开裂和时效后产生的Zr₅Al₃相之间的相互作用,导致塑性异常,仅为5.8%;60、90、120 h时效后合金的压缩屈服强度均在1300 MPa左右,塑性均在15%左右,具有优异的稳定性且断口主要为晶间断裂。

Abstract: Nb₃₇Ti₂₀Al₁₅Zr₁₅Hf₅Ta₅Mo₂W₁(at%) refractory high-entropy alloy was produced by vacuum arc melting. Then the alloy was hot deformed+homogenized, and aged at 750 ℃ for 30-120 h. The as-cast structure, precipitation behavior and mechanical properties of the refractory high-entropy alloy after aging were studied by means of X-ray diffraction, scanning electron microscope, transmission electron microscope and universal mechanical testing machine. The results show that the structure of the as-cast alloy is composed of B2 matrix and antiphase boundaries. After aging, a large amount of vermicular Zr₅Al₃ phase are precipitated within the grain, and rod-shaped Zr₅Al₃ phase are precipitated at the grain boundaries, inducing intergranular fracture. After aging for 30 h, the compressive yield strength of the alloy is 1093.8±7.5 MPa. Due to the interaction between intergranular cracking and Zr₅Al₃ phase after aging, the compressive plasticity is anomaly only 5.8%. After aging for 60, 90, and 120 h, the compressive yield strength of the alloy is about 1300 MPa, and the plasticity is about 15%. It has excellent stability and the fracture is mainly intergranular fracture.

Key words: refractory high-entropy alloy, B2 phase, microstructure evolution, aging, compressive property
