摘要：
As one kind of critical basic materials, high-performance alloys play a vital role in high-end equipment manufacturing, new energy and other strategic emerging industries. With the development and growth of strategic emerging industries in China, demands for alloy materials with high performance will increase substantially. However, preparation of alloy materials needs to consume a large amount of metal mineral resources, which includes various scare metals. At the same time, the social accumulation of scrap alloys will increase year by year, resulting in ecological problems. Therefore, how to achieve coordinated development among resource, development and environment has become an international research hotspot. Circular economy has been considered to be an important way to achieve sustainable development. Cemented carbides, lightweight alloys and high temperature alloys have a wide range of important applications in national economy and defense construction. In this paper, three typical alloys including tungsten carbide cemented carbide, lightweight aluminum alloys and high temperature nickel-based alloys were selected, and their resource reserves, scrap characteristics and recycling technologies were systematically analyzed. Finally, the prospective of alloying recycling in the future was given. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
