Elastic deformation, dislocation-mediated plasticity, twinning-induced plasticity, TRIP, and finally solid-state amorphization. Triggering the next mechanism re- quires the generation of additional defects, i.e., dislocations and/or point defects (vacancies). These multiple mechanisms can interact, leading to a synergy of strengthening processes and a resulting highly complex microstructure. CREDIT University of California San Diego ....

This discovery opens the door to applications in everything from landing gears, to pipelines, to automobiles. The new materials could make these lighter, safer, and more energy efficient. The team, which includes researchers from the University of California San Diego and Berkeley, as well as Carnegie Mellon University and University of Oxford, details their findings in the Jan. 29 issue of ....
