A study on grain growth using a novel grain size calculation tool

Analysis of grain size distribution evolution of steel during recrystallization and grain growth

“…In this study, all the grain size distributions are based on experimental data obtained from laser scanning confocal microscopy images. The images are processed with a novel self-made GUI tool for grain size calculations, called grain size calculator [9], see figure 1. The tool is based on the mean linear intercept method, where multiple lines are drawn on the image and each intercept with a grain boundary is marked and counted together to calculate a mean linear intercept grain size [5].…”

Microstructure evolution and static recrystallization kinetics in hot-deformed austenite of coarse-grained Mo-free and Mo containing low-carbon CrNiMnB ultrahigh-strength steels

“…The prior austenite grain size and their size distributions were calculated semi-automatically from laser scanning confocal microscopy (LSCM) images by linear intercept method using a novel calculation tool developed by one of the authors and described in more details in [23]. In brief, firstly, a linear intercept interval data set is obtained using a self-made GUI tool, grain size calculator [23]. A novel fitting technique is then applied to fit a probability density function to the data set.…”

Influence of Prior Austenite Grain Structure on Hydrogen-Induced Fracture in As-Quenched Martensitic Steels

“…Table 1 summarizes the mechanical properties, average PAG size (d G ), PAG boundary surface area per unit volume (S v ), and PAG aspect ratio (RD/ND) of each steel grade. Mean PAG sizes were calculated with a novel grain size calculating program [31] from all RD-ND, RD-TD, and TD-ND sections, where RD = rolling direction, ND = normal direction and TD = transverse direction. The program utilizes the mean lineal intercept method and provides a good statistical accuracy with over 200 measured points/material.…”
