Description

Technical Field

[0002] Solution treatment refers to a heat treatment process in which the alloy is heated to a high temperature single-phase region and kept at a constant temperature, so that the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain a supersaturated solid solution. Because the operation process is similar to quenching, it is also called "solution quenching". It is suitable for alloys with a solid solution as the matrix and a large solubility change when the temperature changes. Because it is in a metastable state in thermodynamics, dissolution or other transformations will occur under appropriate temperature or stress conditions.
