| 英文摘要: |
| With the continuous advancement of technology, the manufacturing of materials is moving towards high performance. In today's manufacturing industry, the production of high-performance new material components has become an important direction. In particular, the forming of bulk amorphous alloy components is receiving significant attention and is a current focus and challenge of research. Currently, the research on non-crystalline alloy casting forming techniques mainly includes vacuum die casting, vacuum suction casting, water-cooled copper crucible induction melting copper mold casting, etc. This article focused on exploring the impact of process parameters on the glass-forming ability (GFA) in these methods, and listed some amorphous alloy components prepared by casting forming methods and their accuracy. Unlike traditional crystalline materials, non-crystalline alloys have no grain boundaries, dislocations, and other defects. This article also analyzed some common defects in non-crystalline alloys. The forming ability and performance of amorphous alloy components were closely related to the purity of the matrix metal. By comparing amorphous alloys of different purity, the impact of raw material purity on component performance was analyzed. Currently, most amorphous alloy casting has been carried out in a vacuum or air atmosphere, and the impact of different atmospheres on the forming performance of amorphous alloy casting has been studied. In general, the forming and preparation technology of amorphous alloy components have significant application prospects. With the continuous advancement of technology, the efficiency and precision of producing amorphous alloy components will be further improved, bringing greater development opportunities to the high-end equipment manufacturing field. |
