Plastic localization at High Temperature

Check out our latest publication in Acta Materialia: https://lnkd.in/gNftY7e6 Utilizing high-temperature, high-resolution digital image correlation, we’ve been able to observe the temperature-dependence of plastic localization at the nanoscale across a wide field of view. This approach has led to a deeper understanding of the microstructure-dependence of diffusion creep (Coble creep) phenomena during the deformation of …
