中文摘要
在新加坡举行的联合工程基金会会议上(9月10日),24-28,2000),将讨论块体金属玻璃的基本方面和应用的最新进展。 主题包括原子结构,材料合成,玻璃形成能力,以及金属玻璃的物理,化学,热和机械性能。 具有非晶结构的金属玻璃首先由Paul Duwez在20世纪60年代早期使用快速凝固技术合成。 1989年,日本首次在金属玻璃设计方面取得突破,当时成功地用多元素系统合成了大量材料。这些含有多种合金元素的大块金属玻璃(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和稀土元素的非晶合金均已成功合成。BMG构成了一种新的和令人兴奋的金属材料,具有结构和功能用途的有趣特性。在过去的十年里,人们在理解非晶形成能力和合成新型多组元大块非晶合金方面取得了实质性进展。 横截面厚度大于3cm的BMG现在可以通过传统的熔化和铸造技术生产。尽管这一技术上的成功,相稳定性,杂质的影响,局部剪切带的形成,和非牛顿流动行为的基本理解仍然缺乏。
英文摘要
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.***
