We present simulation results based on a phase-field model that describes the migration of recrystallization boundaries into spatially varying deformation energy fields. Energy fields with 2-dimensional variations representing 2 sets of dislocation boundaries lying at equal, but opposite, angles to the moving boundary are considered. The simulations show that the shape and overall migration rat...

During heat treatment, the work piece experiences a range of heating rates depending upon the sizes and types of furnace. When the Al-Si-Mg cast alloy is heated to the solutionizing temperature , recrystallization takes place during the ramp-up stage. The effect of heating rate on recrystallization in the A356 (Al-Si-Mg) alloy was studied using dilatometric and calorimetric methods. Recrystalli...

Ice recrystallization is of great importance to both fundamental research and practical applications, however understanding and controlling ice recrystallization processes remains challenging. Here, we report the discovery of an ion-specific effect on ice recrystallization. By simply changing the initial type and concentration of ions in an aqueous solution, the size of ice grains after recryst...

Control of the material microstructure in terms of the grain size is a key component in tailoring material properties of metals and alloys and in creating functionally graded materials. To exert this control, reliable and efficient modeling and simulation of the recrystallization process whereby the grain size evolves is vital. The present contribution is a review paper, summarizing the current...

Abstract To achieve a desired microstructure and minimize the thickness variation in rolled foils, researchers must understand effects of foil fabrication process variables on evolution. We developed an integrated simulation deformation recrystallization that employs finite element method (FEM) kinetic Monte Carlo (KMC) Potts model, respectively, to investigate evolution during multiple-pass ho...

Abstract With the aim of analyzing post-deformation Recrystallization (PDRX) 22MnB5 steel and grain size evolution after hot forming sheet using BAEHR 805 A/D thermo-mechanical simulator, several isothermal stress relaxation tests were performed in a temperature range 800 to 950 °C, predeformation 0.4 0.8 strain rate 0.01 s −1 . As result deformation, PDRX kinetics can be described based on an ...
