Brown research shows benefits of nano-patterned metals

BROWN UNIVERSITY RESEARCHERS, in collaboration with scientists from the Chinese Academy of Science, have published a new study proving that nano-scale patterning of metals can make them more resistant to fatigue. Above, atomic-scale simulations show how nanotwins align strain-related defects, keeping them from impeding each other and making them reversible. / COURTESY BROWN UNIVERSITY

PROVIDENCE – A new study authored by Brown University researchers shows how metals can be patterned at the nanoscale to be more resistant to fatigue, a condition that results from the slow accumulation of internal damage from repetitive strain. The study, published in the journal Nature, showed that boundaries in a metal’s atomic lattice with…
