Abstract

The invention relates to a method for quantitatively analyzing solid phase dispersion distribution in semi-solid slurry tissue and belongs to the field of metal semi-solid slurry tissue performance analysis. The method includes separating solid phase in the semi-solid slurry tissue out, calculating the total size of the solid phase, calculating and drawing an ideal dispersion degree distribution pattern of the solid phase, and calculating and obtaining dispersion distribution degree coefficient through comparing an ideal distribution state with a real distribution state of the solid phase. With the method for quantitatively analyzing solid phase dispersion distribution in semi-solid slurry tissue, dispersion distribution degree of the solid phase in the semi-solid tissue can be given quantitatively and the range of the dispersion distribution degree is greater than 0 and smaller than 1. A greater number indicates more even distribution degree of the solid phase in the semi-solid tissue and better performance of the semi-solid tissue. The method for quantitatively analyzing solid phase dispersion distribution in semi-solid slurry tissue is simple to operate and convenient to use.

Description

technical field [0001] The invention relates to a method for quantitatively analyzing the dispersion distribution of the solid phase in the structure of semi-solid slurry, which belongs to the field of analyzing the structure and performance of metal semi-solid slurry. Background technique [0002] Semi-solid metal technology is a technology between liquid and solid forming proposed in the 1970s. It has broad application prospects in the fields of automobiles, aviation, and aerospace due to its characteristics of stable filling, high compactness of parts, small thermal impact on the mold, high mechanical properties, and low forming force. Among them, the preparation of a semi-solid metal slurry with a uniform and fine non-dendritic structure, that is, a semi-solid structure in which the spherical solid phase is uniformly distributed and the liquid phase is uniformly distributed around the solid phase, is the most important in the semi-solid metal forming technology. It is a...
