Description

technical field [0001] The invention relates to the technical field of preparation of amorphous alloy materials, in particular to a method for preparing amorphous alloy composite materials. Background technique [0002] Amorphous alloy is a kind of metal material with disordered atomic structure and non-equilibrium energy. Because of its unique structure and properties, it has some properties superior to traditional metals, such as high strength and high stiffness. It is used in aerospace, Medical equipment, 3C electronics and other fields have important application prospects. However, amorphous alloys also have disadvantages such as high brittleness, low thermal conductivity, and low magnetic permeability, which seriously restrict their application. How to comprehensively improve the performance of amorphous alloys is one of the key bottleneck technologies to break through the "application field" of amorphous alloys. [0003] The current method to improve the properties o...
