摘要

我们制备了一种新型铸造高熵合金（HEA），它由 L12 和 B2 两相组成的双相微结构。我们设计的高熵合金实现了显著的强度-韧性平衡（抗拉强度达 1025 兆帕，均匀伸长率达 30%，远远优于电弧熔化和直接铸造的高熵合金）。

Achieving a remarkable strength–ductility combination in a novel casting AlCoCrNi high entropy alloy

We prepared a novel cast high-entropy alloy (HEA) that comprises a dual-phase microstructure with L1₂ and B2 phases. Our designed HEA achieved a remarkable strength–ductility balance (tensile strength of ∼1025 MPa and uniform elongation of ∼30 %, which well outperforms many as-cast HEAs including arc-melting and directly cast HEAs.

期刊介绍： Materials Science and Engineering A provides an international medium for the publication of theoretical and experimental studies related to the load-bearing capacity of materials as influenced by their basic properties, processing history, microstructure and operating environment. Appropriate submissions to Materials Science and Engineering A should include scientific and/or engineering factors which affect the microstructure - strength relationships of materials and report the changes to mechanical behavior.
