  • Investigation of the workability of duplex stainless steel with tensile tests = Ugotavljanje preoblikovalnih sposobnosti duplex nerjavnega jekla z nateznim preskusom
    Arzenšek, Boris ...
    The workability of steels is sligtly dependent on the type of deformed steel, and depends strongly also on test method. The main competent method to investigate the steel workability is the ... examination of specimens taken from the deformation proces and it is not applied in majority of examples. Therefore the workability is tested applying different procedures that enable to make a relative comparison of workability in dependence of deformation conditions and make inferences on true stresses during the treated deformation process. In this work the workabiliy of the duplex stainless steel LDX 2101 was determined with true strain - true stress curves at steel hot rolling temperature with tensile tests in temperature range 850 to 1250oC and deformation velocities 0.01 and 0.001 s-1. The most favourable temperature range for hot deformation of the steel LDX 2101 and the strain hardening were established in dependence of temperature and deformation degree.
