摘要

在形成铝的奥氏体不锈钢中，随着更多的W取代Mo, 336?h在1053?K。电子显微镜显示，由于W的加入，第二相的数量增加，水垢的生长速度变慢。氧化的延迟是由于金属-氧化物界面前W的必要分配。富W第二相与生长的氧化物相互作用，最终在垢内转化为金属W合金的细颗粒。

Effect of tungsten on the oxidation of alumina-forming austenitic stainless steel

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.
