英文摘要： The application of metallic glass composites contain in-situ formed dendrites in the fields of aerospace, defense industry and communication electronic equipment will be constrained due to the microstructure undsignable and uncontrolled. The precipitation behaviors of the dendrite as well as its relationship with the amorphous phase will be carefully studied during the solidification process. The underlying thermodynamic and kinetic mechanism will be illustrated. The formation mechanism of amorphous alloy composites containing dendrites will be understood deeply. Furthermore, the relationship among the microstructure, mechanical properties and solidification controls will be studied to disclose fundamentals of design and solidification control during the preparation of amorphous alloy composite. A technology of preparing the composite with the shape and the well combination of microstructure and mechanical properties will be setup accordingly. On this basis, the parts of excellent performance will be made. The results will enrich the basic theories of design and preparation of amorphous material with solidification control, and promote the development of the discipline itself. On the other hand, it will promote the progress of the preparation of advanced materials and shaping techniques, and lay a solid foundation for the development of China's national defense and economic construction and other fields.
