With this ICME workflow, effective properties at the macroscale could be obtained by taking microstructure morphology and orientation into consideration. An ICME-based vertical integration workflow in two stages is proposed.
The flow curve from virtual test simulation showed good agreement with the flow curve obtained with tensile test in Gleeble ®. FEM-based virtual uniaxial tensile test with Abaqus ® software was used to calculate the effective macroscale flow curves from the phase-field simulated microstructure. Asymptotic homogenization implemented in Homat ® software was used to calculate the effective macroscale thermo-elastic properties from the phase-field simulated microstructure. A single scaling factor introduced in JMatPro ® software minimized the deviation between calculations and experiments. The phase fractions and the phase transformation kinetics simulated by phase-field method agreed well with experiments. The austenite-to-ferrite and austenite-to-bainite transformations during cooling at HAZ were simulated using the Johnson–Mehl–Avrami–Kolmogorov (JMAK) equation implemented in JMatPro ® software and with phase-field modeling implemented in Micress ® software. The resulting phase transformations and microstructure were studied experimentally.
JMATPRO SOFTWARE SIMULATOR
The time–temperature profile at HAZ obtained from FEM simulation was physically simulated using Gleeble 3800 ® thermo-mechanical simulator with a dilatometer attachment. The macroscale simulation of the welding process was performed with finite element method (FEM) implemented in Simufact Welding ® software and was experimentally validated. An integrated computational materials engineering (ICME)-based workflow was adopted for the study of microstructure and property evolution at the heat-affected zone (HAZ) of gas metal arc-welded DP980 steel.
