With the increasing demand for material properties from high-end equipment and cutting-edge technology, the complexity of alloy materials in terms of element types, composition span, microstructure, and other aspects continues to increase. Amorphous alloys are typical complex alloy systems that exhibit molding characteristics and mechanical, physical, and chemical properties that are not present in other alloys. They play an important role in critical fields. Then, the composition space covered by amorphous alloys is huge, and the preparation process depends on environmental atmosphere, high temperature, cooling rate and other conditions, making material research and development extremely difficult.

Material genetic engineering can simultaneously enhance the breadth and speed of material exploration. The Liu Yanhui team, in collaboration with relevant industry enterprises, has built an amorphous alloy digital intelligence research and development platform after nearly two years of technological breakthroughs. This platform deeply integrates the concept of material genetic engineering, artificial intelligence methods, and automatic experimental technology, providing a new mode of "data-driven intelligent design automatic experiment material discovery" for amorphous alloy research and new material exploration (as shown in the figure below). In terms of intelligent design, the team developed GlassChat, an intelligent assistant that can recommend new alloys, based on a professional database of amorphous alloys and field literature, combined with a big language model.
