Microstructural characterization of grade 300 and grade 350 maraging steels and...
Flórez, Mauro Andrés Cerra; Pereira, Úrsula Cid; Cardoso, Jorge Luiz; Oliveira, Francisco José dos Santos; Araújo, Walney Silva; Ribas, Gemma FargasThe electrochemical behavior of solution-annealed grade 300 and grade 350 maraging steels subjected to two different aging temperatures in an aqueous hydrofluoric acid (HF) medium was evaluated. The microstructural and hardness studies showed the effects of the chemical composition and heat treatments on the material properties. Although it is not possible to observe them, the fine intermetallic composites depo...
Alívio de tensões residuais em junta soldada com arame de baixa temperatura de ...
Oliveira, Francisco José dos SantosThe multi-pass welding of thick plates imposes to the welded joint a state of residual stresses that can be very harmful when they are in service. There are various phenomena that can alter the levels of residual stresses after materials welding; one of them is phase transformation. This work presents a comparative study of the levels of residual stresses in three welded joints, produced with different filler m...
