Recrystallization Behavior During Warm Compression of Martensite Steels

PREDICTION OF CRITICAL STRESS AND STRAIN FOR THE ONSET OF DYNAMIC RECRYSTALLIZATION IN PLAIN CARBON STEELS

The aim of the present study is the prediction of critical conditions (including critical strain and flow stress) for the initiation of dynamic recrystallization during thermo-mechanical processing of plain carbon steels. For this propose, torsion tests were conducted at different temperature (1050, 1100 and 1150˚C) and strain rates (0.002, 0.02 and 0.2/s). All flow curves showed a peak st...

Monte Carlo Simulation for Recrystallization in If Steels, Combined with Oim Microstructure

Monte Carlo (MC) simulations for recrystallization were performed using OIM (Orientation Image Microscopy) data sets to define the initial microstructures. Two types of OIM data sets were used as input to the simulations. One type was measured on a warm-rolled interstitial-free (IF) steel sheet. The results were strongly affected by the assumptions used to estimate the stored energy, which is t...

Development of Recrystallization Textures in Deep-Drawing Steels, Measured by X-Ray Diffraction and EBSD

The development of recrystallization textures in two low carbon steels used for deep drawing has been investigated through measurements of global textures (by X-Ray diffraction) and local orientations (by EBSD, Electron Back Scattering Diffraction). The global measurements allow a quantitative description of the recrystallization textures whereas the local measurements allow to identify some of...

Effect of Composition on the Recrystallization Behavior of if Steels During Simulated Hot Strip Rolling

Flow curves are generated in muti-pass torsion tests for a titanium stabilized and a niobium stabilized IF steel. Two types of test schedule are used, one based on plate rolling and the other approximating strip rolling. The purpose of the former is to define the three critical temperatures of steel rolling. The strip schedules are varied in order to investigate the influence of increasing the ...
