Researchers unveil a secret of stronger metals

https://phys.org/news/2022-05-unveil-secret-stronger-metals.html

"grains forming down to nanometer scale... nano-twinning assisted recrystallization... part of crystalline structure flips orientation... could increase metal's strength tenfold... wide range of imaging and measurements to the exact same particles and impact sites... end up getting a multimodal view. We get different lenses on the same exact region and material, and when you put all that together, you have just a richness of quantitative detail about what's going on that a single technique alone wouldn't provide"
