The ESAFORM benchmark 2023: interlaboratory comparison benchmark for the characterization of microstructural grain growth and dynamic recrystallization kinetics of a single-phase Ni-base superalloy

The paper presents a comprehensive benchmark study funded by ESAFORM and conducted at eight European research centers. The study focused on high-temperature tests of the nickel-based superalloy Alloy 625 to evaluate its flow behavior and microstructural evolution, including grain growth (GG) and dynamic recrystallization (DRX). Uniaxial compression tests were conducted at 1050 °C and three strain rates (0.1 s⁻1, 1 s⁻1, and 10 s⁻1). Six test facilities were used, divided into three types: two conventional thermomechanical machines with electric resistance furnaces, two deformation dilatometers with induction heating, and two Gleeble machines with Joule heating.
