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…
