Abstract

Abstract: Rolling process of the 316L/Q370qE clad plate was simulated by Gleeble-3800 thermal compression testing. And the influence of deformation amount, deformation temperature and holding time before deformation on bonding strength of the clad plate was studied by means of tensile testing, hardness testing and microstructure analysis. The results show that the bonding strength gradually increases with the increase of deformation amount, but the increasing trend becomes slower when the deformation amount is greater than 20%. As the deformation temperature increases, the bonding strength first increases and then decreases, and the bonding strength does not change much when the deformation temperature is 1100 ℃ and 1250 ℃. The longer the holding time, the lower the bonding strength of the clad plate is.

Key words: clad plate, hot deformation parameter, bonding strength
