FORMABILITY CHARACTERIZATION OF HADFIELD STEEL

This paper reports the results of an investigation of the mechanical a nd formability properties of Hadfield steel at room temperature. The f ormability characterization was obtained by performing the usual tensi le test, notched-tensile test, hydraulic bulge test and stretch-formin g test. The Forming-limit diagram (FLD) for this steel was characteriz ed. In an attempt to explain the effect of the deformation conditions on the strain-hardening mechanism, the microstructural relationships a re investigated and the deformation characteristics are discussed.
