Outline of Research at the Start

SRO morphology and its effects on strengthening solid-solutions are investigated employing electrical resistivity measurements, STEM and simulations, aming to establish a quantitively framework to resolve the puzzle that whether SRO necessarily strengthens solid-solution alloys.
