- •
Fundamentals of the RVE technique are summarized. It is a good start for keen readers to learn this method.
- •
Statistical quantitative metallography data is used to generate 3D RVEs very similar to the actual microstructure. More than 3000 grains were analyzed in each steel.
- •
Morphology of martensite is included in the 3D RVEs. Hence, steel supplier can optimize both fraction and morphology of martensite in the microstructure.
- •
Using the present model, steel suppliers can predict the UTS of DP500 and DP600 steels with error less than 0.5% before production.
- •
Optimized RVE size, mesh size and element type are reported.
