hot deformation behavior and hot processing map of p92 steel
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.

Hot Deformation Behavior of a New Nuclear Use Reduced The hot deformation behavior and workability of a new reduced activation ferritic/martensitic steel named SIMP steel for accelerator-driven system were studied. The flow curve and its microstructure were studied at 900-1200 °C and strain rate range of 0.001-10 s -1 . Hot working behavior of duplex stainless steel UNS Hot working behavior of duplex stainless steel UNS S32750 characterized by constitutive equations and processing maps Xin ZHAO1, a, Langji CHEN1, b 1 The Six Department, Zhengzhou University of Aeronautics Zhengzhou 450015, China [email protected], [email protected] Abstract. The hot deformation characteristics of duplex stainless steel
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
