      The evolution of retained austenite in a high-carbon high-silicon bearing steel is explored by high energy X-ray diffraction during continuous heating, giving insights on the control of austenite stability or decomposition ...

    • Pandora’s box–influence of contour parameters on roughness and subsurface residual stresses in laser powder bed fusion of Ti-6Al-4V 

      Artzt, Katia; Mishurova, Tatiana; Bauer, Peter; Gussone, Joachim; Barriobero Vila, Pere; Evsevleev, S; Bruno, Giovanni; Requena, Guillermo; Haubrich, Jan (Multidisciplinary Digital Publishing Institute (MDPI), 2020-07-28)
      Article
      Accés obert
      The contour scan strategies in laser powder bed fusion (LPBF) of Ti-6Al-4V were studied at the coupon level. These scan strategies determined the surface qualities and subsurface residual stresses. The correlations to these ...

    • Residual stress distribution of a 6061-T6 aluminum alloy under shear deformation 

      Reyes Ruiz, Carlos; Figueroa, I. A.; Braham, C.; Cabrera Marrero, José M.; Zanellato, O.; Baiz, S.; González de Rivera, G. (2016-07-18)
      Article
      Accés obert
      There is a lack of information with regards to the friction effect in ECAPed aluminum alloys, even though it might substantially modify the deformation at the surface. In this work, the friction effect at the surface and ...

    • Response of ferrite, bainite, martensite, and retained austenite to a fire cycle in a fire-resistant steel 

      Escobar, Julian; Delfino, Pedro; Ariza-Echeverri, Anderson; Carvalho, Felipe; Schell, N.; Stark, A; Rodrigues, Tiago; Oliveira Pedro, Joao; Ávila Díaz, Julián Arnaldo; Goldenstein, Helio; Tschiptschin, Andre (2021-10-30)
