Document Type and Number:

Japanese Patent JP2023141920

Kind Code:

A

Abstract:

To provide a solidification cracking susceptibility evaluation method of an alloy capable of accurately and uniformly evaluating the solidification cracking susceptibility of an alloy for various alloy systems.SOLUTION: A solidification cracking susceptibility evaluation method of an alloy for evaluating the solidification cracking susceptibility during casting of the alloy includes: a structure information acquisition step S01 for acquiring structure information at an arbitrary solid phase ratio for the alloy during solidification; a solid phase bonding ratio calculation step S02 for determining the solid phase bonding ratio calculated from the α phase, the compound phase, and the residual liquid phase by analyzing the acquired structure information and determining the solid phase bonding ratio calculated from the α phase-α phase interface length Lαα, the α phase-compound phase interface length Lαc, and the α phase-liquid phase interface length LαL by the solid phase bonding ratio=(Lαα+Lαc)/(Lαα+Lαc+LαL); and a solidification cracking susceptibility evaluation step S03 for evaluating the solidification cracking susceptibility of the alloy based on the calculated solid phase bonding ratio.SELECTED DRAWING: Figure 1
