Abstract

The invention discloses a method for representing an amorphous alloy microstructure. An electron microscopy three-dimensional reconstruction technology is adopted, the method comprises the steps of performing sample production, transmitting observation records of an electron microscopic image under different angles and compositing a three-dimensional image through a series of two-dimensional images in turn, and the microstructure characteristics of amorphous alloy is represented. According to the method for representing the amorphous alloy microstructure, the difficulty is low, the cost is low, the repeatability is high, the technology is reliable, the three-dimensional structure information is obtained, and the microstructure is regulated and controlled through optimization on rapid solidification technology process parameters on the basis of the representation technology and accordingly the amorphous alloy which is excellent in soft magnetic property and mechanical property can be obtained.

Description

technical field

[0001] The present invention relates to a microstructure characterization method, in particular to a method for characterization of the microstructure of amorphous alloys. The microstructure obtained by the method can provide information on the distribution and connection of atomic clusters in amorphous alloys, and belongs to the structure of amorphous alloy materials. Characterize technical fields. Background technique

[0002] The research results of the last ten years point out that amorphous alloys are densely packed by atomic clusters, and the clusters can share points, lines, and surfaces to connect with each other, thus forming a three-dimensional network structure. The performance design, optimization, and control technologies of amorphous alloys are all based on the short-program structure in amorphous alloys, that is, atomic clusters. Atomic clusters in amorphous alloys are the most basic structural units that determine the macroscopic properties o...
