    • Effect of ageing time on the toughness and the corrosion properties of duplex stainless steel UNS S31803 

      Haupt, William; Silva, Luiz Eduardo; Falcade, Tiago; Santos, Ana Camila Santos dos; Reguly, Afonso (2019) [Artigo de periódico]
      Duplex stainless steels are materials with high mechanical strength, toughness, and corrosion resistance, properties that make them rather appealing for the application on chemical and petrochemical industries. However, ...

    • Electrical conductivity behavior of the aluminum alloy 2024 during artificial aging 

      Diehl, Daniel; Köhler, Carlos Roberto; Schneider, Eduardo Luís; Clarke, Thomas Gabriel Rosauro (2020) [Artigo de periódico]
      Precipitation-hardened aluminum alloys need to be heat treated to achieve the mechanical properties required for their application. The production of these materials can be optimized to make them more attractive and ...

    • Formation of hydrogen blisters during the solution treatment for aluminum alloys 

      Diehl, Daniel; Schneider, Eduardo Luís; Clarke, Thomas Gabriel Rosauro (2021) [Artigo de periódico]
      The solution treatment of aluminum alloys can be restricted by the presence of porosity defects caused by the moisture present in the process or by the hydrated front on the material surface. Hydrogen blisters cause ...

    • Influence of heat treatments on the impact toughness of a Ti-stabilized 12%Cr supermartensitic stainless steel 

      Tavares, Sérgio Souto Maior; Abreu, Hamilton Ferreira Gomes de; Strohaecker, Telmo Roberto; Silva, Mariana Bertonceli; Macêdo, Marcelo Camargo Severo de (2017) [Artigo de periódico]
      The supermartensitic stainless steels (SMSS) are a relatively new class of corrosion resistant alloys developed to obtain a better combination of weldability, strength, toughness and corrosion resistance than conventional ...

    • Oxide formation on NiTi surface : influence of the heat treatment time to achieve the shape memory 

      Hansen, Alana Witt; Beltrami, Lílian Vanessa Rossa; Antonini, Leonardo Marasca; Villarinho, Denis Jardim; Neves, Júlio César Klein das; Marino, Cláudia Eliana Bruno; Malfatti, Célia de Fraga (2015) [Artigo de periódico]
      Several studies regarding superficial treatments of Nitinol (NiTi) shape-memory have been developed aiming to the improve corrosion resistance and to block the Ni release to adjacent tissues. The necessary heat treatment ...
