Metallic glasses have drawn the attention of researchers due to their high strength, hardness, high corrosion, and wear resistance, and ease of thermoplastic forming compared to their counterpart crystalline alloys. While these characteristics are desirable for materials used in extreme environments that often need high corrosion resistance and mechanical strength at elevated temperatures, metallic glasses have found limited use because they crystallize at lower temperatures than the operational temperatures of these applications. Upon crystallization, these characteristics are lost. In recent years, refractory metallic glasses with higher crystallization temperatures have been synthesized, making them potential candidates for use in extreme environments, such as in space and nuclear applications. This review summarizes recently reported metallic glass systems with crystallization temperatures above 700 °C. These systems are discussed in terms of glass forming ability, mechanical properties, and other properties relevant to their use in high temperature applications. This article highlights the challenges in the development and implementation of high-temperature metallic glasses, and discusses the needs and research opportunities that exist for expanding our knowledge of these glasses, including potential routes for improving glass forming ability and mechanical properties.

高温金属玻璃：现状，需求和机遇

与同类的结晶合金相比，金属玻璃具有高强度，高硬度，高耐蚀性和耐磨性，并且易于热塑性成型，因此引起了研究人员的注意。虽然这些特性对于在高温下经常需要高耐腐蚀性和机械强度的极端环境中使用的材料而言是理想的，但由于金属玻璃在比这些应用的工作温度低的温度下结晶，因此发现其用途受到限制。结晶后，这些特性丧失。近年来，已经合成了具有较高结晶温度的耐火金属玻璃，使其成为在极端环境中（例如在太空和核应用中）使用的潜在候选者。这篇综述总结了最近报道的结晶温度高于700°C的金属玻璃系统。这些系统是根据玻璃的形成能力，机械性能以及与其在高温应用中使用相关的其他性能进行讨论的。本文重点介绍了高温金属玻璃的开发和实施中的挑战，并讨论了扩大我们对这些玻璃的知识的需求和研究机会，包括提高玻璃成型能力和机械性能的潜在途径。
