Avaliação da resistência à corrosão e das propriedades mecânicas da junta soldada de aço inoxidável duplex
(Universidade Federal de São Carlos, 2015-12-16)
The corrosion resistance and mechanical properties of hardness and toughness of a welded joint multipass duplex stainless steel have been evaluated under the condition with post-weld heat treatment and as-welded. The ...
Análise de tensões residuais de juntas soldadas em engrenagens de moenda de cana em aço baixa liga
(Universidade Federal de São Carlos, 2015-08-07)
Residual stresses are those which remain in the part when all the external mechanical stress applied previously are removed. These residual stresses often appear in parts subjected to different thermal or mechanical ...
