The ZrCo-based alloys can be not only regarded as promising structural materials but also used in biomedical field without the addition of toxic elements like Cu and Ni. To date, many workers have paid much attention to investigate the GFA and mechanical properties of as-cast ZrCo-based bulk metallic glasses (BMGs) and their composites. The effective evaluation parameter regarding on the GFA has been pinpointed. However, the catastrophic failure after elastic deformation and work-softening of ZrCo-based glassy alloys and composites also pose a threat toward to their applications. In this regard, the microstructural evolution and formation of ductile B2-ZrCo phase have been studied in as-quenched and as-annealed ZrCo-based alloys. The key solution to enhance the plasticity and work-softening revolves three aspects: (1) enhancing formation of the B2-ZrCo phase without too much sacrificing the GFA; (2) restricting the precipitation of brittle eutectic compounds; (3) fabricating the ZrCo-based High Entropy Alloys (HEAs).

ZrCo基合金不仅可以被视为有前途的结构材料，而且还可以用于生物医学领域而无需添加诸如Cu和Ni的有毒元素。迄今为止，许多工人已经非常关注研究铸态基于ZrCo的块状金属玻璃（BMG）及其复合材料的GFA和机械性能。确定了关于建筑面积的有效评估参数。然而，ZrCo基玻璃态合金和复合材料在弹性变形和加工软化之后发生的灾难性破坏也对其应用构成威胁。在这方面，已经在淬火和退火后的ZrCo基合金中研究了韧性B2-ZrCo相的显微组织演变和形成。增强可塑性和工作软化的关键解决方案涉及三个方面：（1）在不过多牺牲GFA的情况下增强B2-ZrCo相的形成；（2）限制脆性共晶化合物的析出；（3）制造ZrCo基高熵合金（HEA）。
