The hot deformation behavior, dynamic recrystallization mechanism and processing maps of Ti-V complex microalloyed high strength steel under temperatures ranging from 840 to 1040 °C strain rates varying 0.01 10 s-1 were studied by using thermal-mechanical simulation (Gleeble-3800), optical microscopy (OM), electron backscatter diffraction (EBSD). true stress-strain curves the investigated obtained different conditions, thermal activation energy was calculated, constitutive equations based on...
The ultra-fine grain structure of Al–Zn–Mg–Cu alloy was prepared by equal channel angular pressing (ECAP) and post cold rolling (CR) combined deformation process. effect different on the microstructure, microhardness corrosion behavior ECAP were studied. results show that with increase deformation, dislocation density increased, second phases deformed obviously refined. Grain refinement mainly due to gradual transformation some subgrain boundaries low angle (LAGBs) alloys into high (HAGBs),...
High‐strength Mg–9Al–1Cu alloy is used as a soluble plugging material for multistage fracturing, and the effect of hot extrusion on its corrosion behavior analyzed. As‐cast (AC) consists α‐Mg, Mg 17 Al 12 , MgAlCu phases. After extrusion, grains are obviously refined average size reduced from 90.67 to 3.75 μm, coarse phases broken distributed at grain boundaries, orientation changes random state obvious {100} texture. The forms both AC as‐extruded alloys mainly pitting corrosion, but reduces...
The microstructural evolution, precipitation behavior, and hardness variation of the Ti-V-Mo complex microalloyed steel during isothermal holding following austenite deformation have been investigated using thermal simulation tester (Gleeble-3800), optical microscope (OM), scanning electron (SEM), backscatter diffraction (EBSD), transmission (TEM), Vickers tester. results indicate that microstructure transforms from to ferrite as time increases 0 s 5400 at 630 °C, with primarily comprising...
The hot deformation behavior ( T = 800–1100 °C, 0.01–10 s −1 ) of 40CrNiMo steel for wind turbine pulley shafts was studied by Gleeble‐3800 thermomechanical simulator. A constitutive equation and processing map are established based on the friction temperature correction curves. most available parameters determined combining microstructure analysis. fields effective strain under different conditions simulated Deform‐3D software. results indicate that effect flow curves is greater than rise,...
