Abstract Numerical algorithm is suggested for calculation of the content of s -phase in HAZ metal of multipass butt-welded joints on duplex steel DSS 2205. Experimental temperature-time diagrams of formation of s-phase under isothermal conditions at different temperatures are used in combination with thermal cycles of points of welded joint HAZ.
