    Improvement of the Turbine Main Stop Valves with Flow Simulation in Erosion by Solid Particle Impact CFD by Z. Mazur, G. Urquiza, R. Campos

    Published 2004-01-01
    “…Because the entire flow to the turbine during start ups is carried by the MSVBV it is subject to serious solid particle erosion problems and requires frequent replacement to avoid the catastrophic damage which can occurred when the MSVBV skirt eroded through causing large pieces of metal to be carried directly into the turbine. For some of the most important geometric parameters of the MSVBV, design recommendation have been made.…”

    L’applicazione della diffrattometria dei raggi X per l’analisi del cedimento dei componenti meccanici by Mario Guagliano

    Published 2013-04-01
    “…X-ray diffraction is a well-known experimental technique for measuring residual stresses in metallic materials. If XRD is applied to the fracture surface of a broken part it becomes a fractographical technique, that is to say that it is possible to relate the results of the measures to the loading condition that lead a component to fail. …”
