Weldability investigation steel P 91 by weld thermal cycle simulationDunđer, Marko (Avtor) Samardžić, Ivan (Avtor) Vuherer, Tomaž (Avtor) weldingP 91hardnessimpact energycoolingThis paper elaborates results of hardness and impact energy of thermal cycle simulated specimens of high-alloy steel P 91 and their dependence on cooling time from 800 to 500 °C. Results were obtained by measuring hardness HV 1 and by experimental testing of Charpy notched specimens. Metallographic analysis of samples was performed on scanning electronic microscope.20152016-05-11 03:53:38Znanstveno delo59263ISSN: 1334-2576UDK: 621.791.052:669.15OceCobissID: 524301593COBISS_ID: 18359062ISSN pri članku: 1334-2576NUK URN: URN:SI:UM:DK:XYIZCCS3sl
