In-situ tensile test scanning electron microscopy dataset for solutionized Inconel 718

High-resolution Digital Image Correlation (HR-DIC) was performed on an Inconel 718 specimen, which was subjected to a heat treatment to form a fully solutionized system. In-situ measurements in the small strain regime were made through SEM imaging, followed by HR-DIC to extract quantitative representations of the strain and in-plane displacement induced by deformation events during plastic deformation., Material: The present study investigated a nickel-based superalloy, Inconel 718. The Inconel 718 material was subjected to an annealing treatment at 1050◦C for 30 minutes, followed by water quenching to produce a nearly random texture and a grain size distribution centered at 65 μm.
Mechanical Testing: Flat dogbone-shaped specimens were prepared for testing with a gauge section measuring 1×3 mm2. Tensile loading was conducted at room temperature under a quasi-static strain rate using a custom 5000 N in situ load stage. The loading was intermittently interrupted at four points through past yield to acquire backscatter SEM images. Load was not removed during the SEM imaging. Macroscopic engineering strain was measured in situ using fiducial markers positioned at both ends of the gauge length, while macroscopic engineering stress was determined by dividing load cell output by the sample cross section.
