摘　　要：Ce基块体非晶合金具有弹性模量低、玻璃化转变温度低、非晶形成能力良好等特点,与传统的Zr基、Ti基、Fe基、Pd基等体系的块体非晶合金相比,Ce基块体非晶合金在过冷液相区内进行均匀塑性变形加工时所需的温度条件更低,由于具有与塑料材料相似的低温热塑性行为特征,因此也被人们称为金属塑料。本文主要介绍了Ce-Al-M、Ce-Al-Cu-X、Ce-La系和Ce-Ga系等块体非晶合金体系,并结合Ce基块体非晶合金不同于传统非晶合金的独特微观结构特征和性能优势,对其在微器件制造、数据存储等领域的应用前景进行了讨论,同时针对Ce基块体非晶合金研究目前存在的问题以及未来发展的方向进行了分析。Ce-based bulk amorphous alloys have the characteristics of low elastic modulus, low glass transition temperature, and good glass formation ability, etc. Compared with the traditional Zr-, Ti-, Fe-, Pd-based and other bulk amorphous alloys, Ce-based bulk amorphous alloys require lower temperature conditions for uniform plastic deformation in the supercooled liquid region. Due to low-temperature thermoplastic behavior characteristics similar to plastics, Ce-based bulk amorphous alloys are also called metallic plastics. In this paper, we mainly introduced Ce-Al-M, Ce-Al-Cu-X, Ce-La series and Ce-Ga series bulk amorphous alloys. Different from the traditional amorphous alloys, these Ce-based bulk amorphous alloys exhibit unique microstructure features and performance advantages. Their application prospects in the micro-device manufacturing, data storage and other fields were discussed. The existing problems in the present research of Ce-based bulk amorphous alloys and their development directions in the future were analyzed as well.
