DOI: 10.1126/science.abh0700
Abstract: Locking structure to high temperature Because of atomic diffusion, metal alloys with nanometer-sized crystal grains do not retain their structure at high temperature. Xu et al. found that a minimum-interface structure allows a supersaturated aluminum-magnesium… read more here.
