The Assessment of the Microstructure and Selected Mechanical Properties of Butt Joints in Ferritic-Austenitic Duplex Steel
The paper presents results of microscopic tests as well as results of tests concerning mechanical properties of MAG (136) welded joints in duplex steel X2CrNiMoN22-5-3 (1.4462). The research involved metallographic tests of the base material, heat affected zone and weld metal as well as Vickers hardness tests, static tensile tests, bend tests and the identification of a ferrite content obtained using a ferritiscope. The results of observations involving the microstructure of the particular zones of the welded joint as well as the quantitative analysis of phases and the results of the tests concerning the mechanical properties of the joints enabled the formulation of conclusions regarding the microstructure and the mechanical properties of the test joints.
