Abstract:Ce-based bulk amorphous alloys have the characteristics of low elastic modulus, low glass transition temperature, 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 introduce 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 are discussed. The existing problems in present research of Ce-based bulk amorphous alloys and their development directions in the future are analyzed as well.
