金属塑料的发明

Invention of cerium based metallic plastics

  • 摘要: 铈基非晶态金属塑料是一种新的块状非晶合金材料,它具有低于开水温度(100℃)的玻璃转变温度.室温时的强度和超高强度铝镁合金相近.该块体非晶合金在开水中表现出超塑性, 可以像聚合物塑料那样进行复杂的变形加工, 因此被命名为“非晶态金属塑料”(简称“金属塑料”).这种新材料不仅具有潜在的应用前景,而且具有重要的基础研究的价值,是一个理想的研究玻璃转变、玻璃形成液体性质等相关问题的新材料.另外,金属塑料作为一种新的概念,开辟了一个新的金属材料研究方向.文章简要介绍了该金属塑料的合成、性能及潜在的应用.

     

    Abstract: Amorphous metallic plastic based on cerium is a new class of bulk metallic glasses with an ultralow glass transition temperature much lower than the boiling point of water close to room temperature, at which temperature it′s high strength is comparable to that of super-strength Al-and Mg-based crystalline alloys. In near-boiling water these metallic plastics show superplasticity and good workability similar to some typical polymeric glasses, and thus have great potential in applications. A new research area devoted to this class of materials and fundamental studies of the glass transition and supercooled liquid state is now developing. In this paper we briefly describe the synthesis, properties and potential applications of cerium based metallic plastics.
