Effect of PWHT on the dissolution of δ-ferrite in the welded joint of 12Cr–1Mo steels for steam turbines

Effect of PWHT on the dissolution of δ-ferrite in the welded joint of 12Cr–1Mo steels for steam turbines

In this research work, the optimal parameters of post welding heat treatment (PWHT) for 12Cr–1Mo Steel in the welding condition are determined. The PWHT aims to decrease δ-ferrite percentage in the interface of the heat-affected zone (HAZ) and partially melted zone (PMZ). The parameters of post weld...
