Brown University Scientists Discover New Principle in Material Science


April 7, 2010

necklace-like patterns of crystal defects A research team led by Brown University engineers has discovered a new mechanism that governs the peak strength of nanostructured metals. The team found that the deformation of nanotwinned metals is characterized by the motion of highly ordered, necklace-like patterns of crystal defects called dislocations. The finding, published in Nature, could lead to stronger and more ductile metals. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
