Universal alignment of defect thermodynamics in hematite

Abstract First-principles defect calculations in hematite ( α -Fe 2 O 3 ) suffer from a >2 eV spread in reported formation energies, arising from (i) metastable or delocalized charge states and (ii) inconsistent error cancellation with chemical-potential boundaries across stud...

Interface engineering enables fast bainitic transformations with minimal alloying

Abstract Fine microstructures in steels are commonly produced by the low-temperature decomposition of austenite. Bainite is one such microstructure, combining high strength and excellent toughness, but its formation kinetics is sluggish. Here, we demonstrate a strategy to acceler...
