摘要：

In the present work the microstructure and the strain induced phase transformation of a Lean Duplex Stainless Steel (LDSS) were studied. Sheet samples were cold rolled, the number of samples was nine; the applied deformation was up to 80%. The magnetization curves were measured by a single sheet tester-type magnetic property analyzer. The series of symmetrical minor hysteresis loops and the saturation loop were measured. Our novel data evaluation technique was applied for data evaluation of the magnetic measurements. This method is based on the multiphase-hyperbolic model of magnetization and it is called model based data evaluation (MBDE) technique. This method allowed us to separate the magnetic contribution of ferrite and martensite phases in the tested LDSS. Several new details of the kinetics of austenite -> martensite strain induced phase transformation were clarified.
