Behavior of MnS inclusions during homogenization process

Jan 01, 2021 · Numerous studies [10,11,12,13] have been carried out to investigate the behavior of the elongated MnS in rolled steel during homogenization. Significant shape change of MnS from slender to spindle-liked or spherical was identified during soaking after hot-rolling process, but these methods to change MnS morphology in rolled steel are not practical. Constitutive Modeling, Microstructure Evolution, and May 13, 2014 · A constitutive equation was established to describe the deformation behavior of a nitride-strengthened (NS) steel through isothermal compression simulation test. All the parameters in the constitutive equation including the constant and the activation energy were precisely calculated for the NS steel. The result also showed that from the stress-strain curves, there existed two different linear

Creep properties, creep deformation behavior, and

Jan 10, 2018 · Creep deformation behavior and microstructure evolution of G115 steel were systematically investigated for temperatures of 625675 °C under uniaxial tensile stress of 120220 MPa.The relationship between minimum creep rate and applied stress followed the Hot Deformation Behavior of GH738 for A-USC Turbine BladesNov 01, 2015 · The processing map was developed based on flow stress data and dynamic materials model (DMM). The map shows a dynamic recrystallization (DRX) domain in 1 050 °C to 1 150 °C and 0.01 sâ1 to 1.0 sâ1 strain rate range with a peak efficiency of 45%, which is considered to be the optimum region for hot working. Hot Deformation Behavior of a New 9% Cr Heat Resistant The hot deformation behavior of a new heat resistant steel G115 designed for 650 °C ultra-supercritical (USC) power plants was experimentaly studied. Hot compression test was carried out in the temperature range of 9001200°C and the strain rate range of 0.120 s1 by using Gleeble-3800 thermal-mechanical simulator, and the corresponding flow curves were obtained.

Hot Deformation Behavior of a New Nuclear Use Reduced

Nov 23, 2018 · 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 9001200 °C and strain rate range of 0.00110 s1. The results showed that the deformation behavior of the SIMP steel during hot compression could be Hot deformation behaviors of a 9Cr oxide dispersion Jul 23, 2019 · The hot deformation behaviors of a 9Cr oxide dispersion-strengthened (9Cr-ODS) steel fabricated by mechanical alloying and hot isostatic pressing (HIP) were investigated. Hot compression deformation experiments were conducted on a Gleeble 3500 simulator in a temperature range of 9501100°C and strain rate range of 0.0011 s1. The constitutive equation that can accurately Numerical Analysis on Hot Stamping of B Pillar Hot stamping of ultra high strength steel offers the possibility to reduce the weight of automobiles, while meeting the safety requirements. In hot stamping processes, the blank is hot formed and quenched in a water-cooled tool to achieve high strength. Hot Deformation Behavior and Hot Processing Map of P92 Steel
