Plastic deformation behavior and processing maps of a Ni-based superalloy

“…6 mation behavior and microstructure evolution of cast-extruded AZ31B magnesium alloy by using processing maps, the optimal region for hot working has been observed at a strain rate of 0.01 s À1 and the temperature of 673 K. Transmission electron microscope and optical microscope were used in the verification of the established processing maps in their paper. Pan et al [6] investigated the characterization of hot deformation behavior of Ni-base superalloy Rene'41, microstructure evolution was discussed in this article to support the parameters based on the processing maps, the grain sizes of the samples after different deformation conditions demonstrate that the instability domains and the optimum deformation parameters based on the processing maps are reliable. Fang et al [8] studied processing maps of FGH96 alloy during two-pass hot deformation and found the optimum deformation domains, microstructure evolution was also discussed to support the processing maps.…”

“…Based on the dynamic materials modeling the processing maps of a Ni-based superalloy was established and the optimum processing conditions was determined on the basis of the processing maps in this paper. Transmission electron microscope and optical microscope, which have been proven effective [6][7][8][24][25], were also used to verify the established processing maps. In the instability domains, the grain sizes and the density of dislocation are much larger than in other domains.…”

“…Extensive researches have been conducted about the hot deformation behavior and processing maps of superalloys, and most of them are try to establish processing maps through experiments and then directly figure out the peak efficiency domains [1][2][3][4][5][6]. Wu and Liu [7] studied hot compressive deformation behavior of a new hot isostatically pressed Ni-Cr-Co based powder metallurgy superalloy, the result shows that the processing maps of this alloy have several peak efficiency domains.…”

Characterization of the Hot Deformation Behavior of Cu–Cr–Zr Alloy by Processing Maps

“…The value g is higher, and the workability is better in this deformation domain. This demonstrates that the material deformed at these conditions with high efficiency of power dissipation shows good workability [26]. At the strain of 0.5, two instability domains were observed in the processing map: domain B occurs in the temperature range of 650-850°C and the strain rate range of 1-10 s -1 .…”

Investigation on Hot Deformation Behavior and Hot Processing Map of BSTMUF601 Super-Alloy

“…However, little research has been carried out on investigating the manufacturing technologies for this alloy, especially analyzing the processes to attain a fine and uniform microstructure in a hot-wrought/rolled state. The flow stress is the most basic parameter for characterizing plastic deformation properties of metals and alloys, and it determines the load and energy needed during the plastic deformation [4]. In recent years, the processing map based on the dynamic materials model (DMM) has been considered an important method for optimizing hot working processes and controlling the microstructure in the forming process [5,6].…”
