Resistência ao desgaste abrasivo da liga Fe66B30Nb4 processada por conformação por spray
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, , 17/12/2009)Aiming at the improvement of the wear resistance of a glass former composition, the Fe66B30Nb4, the alloy was modified with the addition of Ti, resulting in the theoretical compositions: Fe63B29Nb4Ti4 (SF1) and Fe65B30Nb4Ti1 ... -
Microstructure, corrosion, and wear resistance of a boron-modified duplex stainless steel produced by laser powder bed fusion
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 18/03/2024)A duplex stainless steels (DSS) containing 0.3 and 0.6 wt.% of boron were produced by laser powder bed fusion (L-PBD) with parameters based on Box-Behnken design. The microstructure was evaluated by XRD, OM, SEM, EBSD, ...
