Effect of Alloying Additions on the Oxidation of High Speed Steels under Dry and Wet Conditions () 摘要:An investigation has been carried out into the effects of chromium and vanadium content on the oxidation rate and on the adhesion of oxide scales grown on three different chemical compositions of high speed steels under dry and wet conditions. The oxidation tests were carried out......
