Abstract
|
|
|
|
As more W replaced Mo in alumina-forming austenitic stainless steels, weight gain by oxidation decreased after 336?h at 1053?K. Electron microscopy revealed slower growth of scale in the presence of more numerous second phases by W addition. The retardation of oxidation was attributed to the necessary partitioning of W in front of the metal-oxide interface. The W-rich second phases interacted with growing oxides and finally transformed to fine particles of metallic W alloy within the scale.
