  • Effect of Preheating on the Residual Stress and Material Properties of Inconel 939 Processed by Laser Powder Bed Fusion 

    Malý, Martin; Nopová, Klára; Klakurková, Lenka; Adam, Ondřej; Pantělejev, Libor; Koutný, Daniel (MDPI, 2022-09-13)
    One of the main limitations of laser powder bed fusion technology is the residual stress (RS) introduced into the material by the local heating of the laser beam. RS restricts the processability of some materials and causes ...
  • Damage Evolution in Thermomechanical Loading of Stainless Steel 

    Petráš, Roman; Škorík, Viktor; Polák, Jaroslav (Elsevier, 2016-06-20)
    Superaustenitic stainless steel Sanicro 25 has been subjected to in-phase and out-of-phase thermomechanical fatigue (TMF). Different amplitudes of mechanical strain and the changes of the temperature in the interval 250 ...
