hot deformation behavior and hot processing map of p92 steel

Flow behavior modeling and processing maps for P91

identify the hot working process parameters and control the microstructure of materials1, 18-20. There are many academic studies carried out on the hot deformation behavior of P91 steel. C. Samantaray et al. built the sine-hyperbolic constitutive equation and processing map over a wide range of strain rate 0.001-100 s1. However, whether the Flow stress modeling, processing maps and microstructure Apr 27, 2020 · During the hot forming process, deformation defects caused by the instable plastic flow of the materials can be reduced and avoided on the basis of the investigation of the processing maps. In this paper, the effects of thermo-mechanical parameters on the hot deformation behavior of 05Cr17Ni4Cu4Nb martensitic stainless steel are investigated.

NOPR:Flow behavior modeling and processing maps for P91

The processing maps have been developed based on the dynamic materials model (DMM) and Prasads instability criterion. The optimum hot deformation regions at 0.7 strain have at the temperature of 1000-1175 °C and strain rate of 0.05-0.14 s 1 ; at the temperature of Hot Deformation Behavior and Processing Maps of Fe-30Mn Hot deformation behavior of Fe-30Mn-0.11C steel was investigated. Hot compression tests were carried out at various temperatures ranging from 800 °C to 1200 °C and at different strain rates of 0.01 s -1 to 10 s -1 . The constitutive equation based on peak stress was established. H
