An open challenge on structural biomaterials is to obtain low-cost Ti-alloys with high elastic admissible strength (the ratio of yield strength to modulus). To reach this goal, we designed and characterized three quaternary alloys from the Ti-Nb-Fe s

Compositional analysis on the reverted austenite and tempered martensite in a Ti-stabilized supermartensitic stainless steel: Segregation, partitioning and carbide precipitation

Autor: J. Rodriguez, G.A. Faria, Antonio J. Ramirez, Jonathan D. Poplawsky, João Pedro Oliveira, J.D. Escobar, Paulo Roberto Mei, S. Suresh Babu, Camilo A.F. Salvador
