Title:
METHOD FOR REDUCING RESIDUAL STRESS OF HETEROGENEOUS BRAZED JOINT
Document Type and Number:
WIPO Patent Application WO/2024/007453
Kind Code:
A1
Abstract:
A method for reducing residual stress of a heterogeneous brazed joint. When the temperature of the brazed joint is reduced to a certain temperature, heating treatment is performed to generate micro-plastic deformation and micro-precipitation and reduce the residual stress, cooling is performed again to generate the residual stress, and then the stress is reduced by raising the temperature, so that the temperature of the joint is reduced and the residual stress of the joint is reduced in a circulating process.
