As Strong As Steel

摘要

The development of nanoscale materials structuring has allowed for a revolution in metallurgy; steel strengths of over 2 000 MPa are now achievable through appropriate grain-size refinement strategies. However, while high strength can now be achieved, the ductility of these materials must be investigated in order to fully assess the technological viability of these newly development materials. As part of this effort, Olivier Bouaziz, a researcher with the steel giant ArcelorMittal, has explored the relationship between the ductility and microstructural scale of single-phase steels produced through various advanced metallurgical techniques, through uniform elongation and area-reduction fracture strain studies.
