This transition {microstructureTransition} microstructure, consisting in spatial variations of grain {sizesGrain} size and/or γʹ {precipitationPrecipitation}, poses difficulties in providing insights into effective modeling strategies in aero-engines. To characterize viscoplastic behavior at intermediate temperatures, stress {relaxationStress} relaxation tests were employed using {AD}730™ {superalloyAD}730TM superalloy. A single-crystalline version of {AD}730™ was used to isolate the effects of different {precipitationPrecipitation} states (ranging from 15 to 300 nm in size), at 700 °C and 800 °C. The results reveal a significant impact at 700 °C, while no substantial impact was observed at 800 °C. Additionally, precise specimen machining was conducted in different radial zones of a dual {diskDual} disks to explore the influence of various grain {sizeGrain} size gradients, on viscoplastic behavior at both 700 °C and 800 °C. The findings indicate a progressive viscoplastic behavior along the gradient of grain {sizeGrain} size for both testing temperatures. Finally, the viscoplastic behavior of transition specimens was analyzed within the framework of a grain-sensitive phenomenological model.
