In this United Engineering Foundation conference in Singapore (Sept. 24-28, 2000) the recent progress in both fundamental aspects and applications of bulk metallic glasses will be discussed. Topics include the atomic structure, materials synthesis, glass-forming ability, and physical, chemical, thermal, and mechanical properties of metallic glasses. Metallic glasses with amorphous structures were first synthesized by Paul Duwez in the early 1960s using rapid solidification techniques. A breakthrough in the design of metallic glasses was first made in 1989 in Japan when bulk quantities of material were successfully synthesized with multi-element systems. The critical cooling rates of these bulk metallic glasses (BMGs) containing multiple alloying elements approach those of oxide glasses. At present, BMGs based on Zr, Ti, Ni, Fe, Co, Al, Mg, and rare-earth elements have all been successfully synthesized. %%%BMGs constitute a new and exciting class of metallic materials with interesting properties for structural and functional use. For the past decade, substantial advances have been achieved in understanding the glass forming ability and synthesizing new bulk amorphous alloys containing multi-components. BMGs with cross-sectional thickness greater than 3 cm can now be produced by conventional melting and casting techniques. Despite this technological success, fundamental understanding of phase stability, impurity effects, localized shear band formation, and non-Newtonian flow behavior is still lacking.***

在新加坡举行的联合工程基金会会议（2000 年 9 月 24 日至 28 日）上，将讨论大块金属玻璃的基本方面和应用方面的最新进展。 主题包括金属玻璃的原子结构、材料合成、玻璃形成能力以及物理、化学、热和机械性能。 Paul Duwez 在 20 世纪 60 年代初首次使用快速凝固技术合成了具有非晶结构的金属玻璃。 金属玻璃的设计首次于 1989 年在日本取得突破，当时用多元素系统成功合成了大批量材料。这些含有多种合金元素的块体金属玻璃（BMG）的临界冷却速率接近氧化物玻璃。目前，基于Zr、Ti、Ni、Fe、Co、Al、Mg和稀土元素的BMG均已成功合成。 %%%BMG 构成了一类令人兴奋的新型金属材料，具有令人感兴趣的结构和功能用途特性。在过去的十年中，在了解玻璃形成能力和合成含有多组分的新型大块非晶合金方面取得了实质性进展。 现在可以通过传统的熔炼和铸造技术生产横截面厚度大于 3 厘米的 BMG。尽管取得了技术上的成功，但仍然缺乏对相稳定性、杂质效应、局部剪切带形成和非牛顿流动行为的基本了解。***
