Abstract
The thermal oxidation resistance of a 25 Cr-1.5 Al steel has been tested after the addition of various quantities of yttrium. The oxides formed at high temperature have been examined with the ESCA technique, particularly in the first stages of formation. The authors suggest that yttrium operates in various ways, depending on the composition of the basic alloy, the quantity of yttrium added, the surface and bulk pre-treatments and the work temperature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
