| 中文摘要: |
| 高熵合金作为一类新型多组元的复杂合金材料，因其独特的优异性能引发了广泛的关注。与传统合金相比，高熵材料的制备工艺与传统材料具有相似性，但也有其特殊性。从不同维度出发，讨论与分析了各种形态高熵材料的制备成形加工工艺，主要包括三维块体材料、二维薄膜及薄板材料、一维纤维材料以及零维粉末材料。主要总结了电弧熔炼法、感应熔炼法、增材制造法、粉末冶金法、磁控溅射、激光熔覆等制备技术;此外，讨论了通过变形加工工艺制备高熵薄板、丝材及纤维的方法。旨在对已开发的高熵材料的制备成形及加工工艺进行总结及讨论，为以后面向“工艺”技术开发新型的高熵材料提供技术支持。 |
| 英文摘要: |
| High-entropy alloy, as a new kind of multi-component complex alloy material, has attracted extensive attention because of the unique excellent properties. Compared with traditional alloys, the preparation process of HEMs is roughly similar to that of traditional materials, but it also has its particularities. The preparation and forming processes of various forms of high-entropy materials (HEMs) were discussed and analyzed from different dimensions, including three-dimensional bulk materials, two-dimensional film and sheet materials, one-dimensional fiber materials, and zero-dimensional powder materials. The preparation methods were mainly summarized, such as arc melting method, induction melting method, additive manufacturing method, powder metallurgy method, magnetron sputtering technology, laser cladding technology, etc. Moreover, the preparation method of high-entropy sheets, wires and fiber through deformation processing was explored. The work aims to summarize and discuss the preparation, forming and processing technology of developed high-entropy materials, and to provide technical support for developing new high-entropy materials for “process” technology in the future. |
