Abstract
The interfacial structures and behaviors are critical in determining the material properties. Our study aims to investigate such unique interfacial structures and behaviors in multiphase systems involving complex compositions. Herein, we report the divergent interfacial behaviors of the L12–L12, B2–B2, and L12–B2 boundaries prepared via the bonding of AlCoCrFeNi2.1 eutectic high-entropy alloys (HEAs). Specifically, interfacial dynamic recrystallization (DRX) occurs in the L12–L12 boundary owing to the thermostrain-induced grain boundary evolution. In contrast, the bonding of the B2–B2 boundary may be realized by interface diffusion, and no evident DRX occurs owing to the small interfacial shear strain. The DRX grains only developed on the L12 side in the L12–B2 boundary because of the difference in the intrinsic structural traits between L12 and B2. The diffusion of elements contributed to the bonding of this dissimilar boundary. Moreover, a strain-induced B2II precipitation phenomenon surrounding the bonding interface was revealed because of the high defect-precipitation sensitivity of HEAs. The B2II particle precipitation depleted the Al and Ni within the matrix, leading to L12 disordering. The Zener pinning effect exerted by B2II precipitates was quantitatively evaluated by calculating the corresponding limited grain radius RL = 1.8 µm. This pinning effect of B2II precipitates and the sluggish diffusion effect may induce temperature-dependent DRX behaviors of the L12–L12 boundary. This study reveals the understanding of the unique interfacial behaviors of multiphase HEAs and provides new insights into the effects of multiple phases, complex composition, and interfacial precipitation on interfacial evolution.
摘要
界面的结构和行为对材料的性能具有重要的影响. 本文旨在研究复杂成分多相体系材料中这些独特的界面结构和行为. 我们报道了通过连接AlCoCrFeNi2.1共晶高熵合金所获得的L12–L12, B2–B2, L12–B2三种界面迥异的界面行为. 具体是, 由于热-应变诱导的晶界演化, 在L12–L12界面附近出现了明显的界面动态再结晶. 相反, 由于极少的界面应变, B2–B2界面几乎没有发生动态再结晶, 其连接可能是由于扩散引起的. 由于L12相和B2 相本征的结构差异, 在L12–B2界面处只在L12 相侧发生了动态再结晶. 这类异质界面的连接是由于界面元素的扩散. 另外, 由于高熵合金高的缺陷-析出敏感性, 在连接界面附近出现了应变诱导析出的B2II相. B2II相的析出消耗了基体中的Ni, Al元素, 造成了L12相的无序化. 通过定量计算相应晶粒的极限尺寸评估了这些B2II相带来的Zener钉扎效应. 这种B2II相的钉扎作用及元素的缓慢扩散效应可能导致了L12–L12界面温度依赖的动态再结晶行为. 本研究有助于理解多相高熵合金独特的界面行为, 并为多相、复杂成分、界面析出等因素对界面演化的影响提供了新的认识.
