Chemical gradients across phase boundaries between martensite and austenite in steel studied by atom probe tomography and simulation
O. Dmitrieva, D. Ponge, G. Inden +4
Partitioning at phase boundaries of complex steels is important for their properties. We present atom probe tomography results across martensite / austenite interfaces in a precipi…

Sustainable steel through hydrogen plasma reduction of iron ore: process, kinetics, microstructure, chemistry
I. R. Souza Filho, Y. Ma, M. Kulse +4
Fe- and steelmaking is the largest single industrial CO2 emitter, accounting for 6.5% of all CO2 emissions on the planet. This fact challenges the current technologies to achieve c…

Nanoscale austenite reversion through partitioning, segregation, and kinetic freezing: Example of a ductile 2 GPa Fe-Cr-C steel
L. Yuan, D. Ponge, J. Wittig +3
Austenite reversion during tempering of a Fe-13.6Cr-0.44C (wt.%) martensite results in an ultrahigh strength ferritic stainless steel with excellent ductility. The austenite revers…
