Abstract

The invention belongs to the technical field of metal functional material preparation, and particularly relates to a process method for regulating and controlling casting temperature of an amorphous alloy melt. The method comprises the following steps that S1, association relationships between different cooling parameters and the lowest casting temperature of the amorphous alloy melt are established; S2, according to the association relationships in the step S1, the lowest casting temperature and the related cooling parameters are selected; and S3, under the conditions of the set lowest casting temperature and the selected cooling parameters, the amorphous alloy melt is rapidly solidified into an amorphous alloy thin strip. According to the provided process method for regulating and controlling the casting temperature of the amorphous alloy melt, the method is suitable for preparing an amorphous alloy material from an alloy melt through a rapid cooling method and is particularly suitable for preparing an iron-based amorphous alloy; and particularly, the method can reduce the casting temperature of the amorphous alloy melt by improving the cooling capacity of a cooling roller underthe condition that components of the iron-based alloy melt greatly fluctuate, and then the performance of the amorphous alloy is improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of metal functional materials, in particular to a process method for regulating the casting temperature of an amorphous alloy melt. Background technique [0002] Since the amorphous alloy is obtained by direct supercooling and solidification of the alloy melt, the non-equilibrium preparation method is adopted. The structure and properties of the amorphous alloy are closely related to the preparation process. Lowering the casting temperature of the alloy melt can change the properties of the amorphous alloy. Microstructure, so any changes in the preparation process and solidification process of amorphous alloys will lead to obvious changes in the structure and properties of amorphous alloys. [0003] Taking the iron-based amorphous alloy as an example, the iron-based amorphous alloy is formed by directly solidifying the alloy melt structure. During the natural cooling and solidification process...
