Deformation and fracture behavior of the P91 martensitic steel at high temperatures

Original language description

The stress relaxation behavior of the P91 martensitic steel is tested for the temperature range 400-600 degrees C in order to investigate the plastic deformation and fracture processes. The repeated relaxation tests are performed on the tensile specimens at the stress level of 95% of the ultimate tensile stress. The deformation mechanisms are analyzed in terms of an activation volume, dislocation density and velocity, a thermal stress component and a strain rate hardening. The deformation is driven by the dislocation glide. Short range interactions between dislocations and a lattice become dominant at the studied temperature range. The dislocations are able to overcome a pinning effect by the thermal activation at 600 degrees C. (C) 2016 Elsevier B.V. All rights reserved
