Microstructure-dependent local strain behavior in polycrystals through in situ scanning electron microscope tensile experiments

M. A. Tschopp, B. B. Bartha, W. J. Porter +2

Digital image correlation of laser-ablated platinum nanoparticles on the surface of a polycrystalline metal (nickel-based superalloy Rene 88DT) was used to obtain the local strain…
