Abstract
AbstractThe Structure and Adhesion of Oxide Scales on FeNiMo and FeCrMo Alloys A preliminary study has been made of the structure and adhesion of oxide scales formed on Fe‐1.8 wt.% Ni‐0.3wt.% Mo and Fe‐1wt.% Cr‐0.5wt.% Mo in oxygen at 930°–1250°C.From 930°–1250°C, the FeNiMo alloy oxidised at a slower rate that the FeCrMo alloy, and both alloys oxidised at a slower rate than high‐purity iron.Hot bend tests and hot tensile tests of a scale‐metal joint revealed that the scales comprised a strongly adherent inner layer (enriched in CrMo or Ni) and a weakly coherent bulk structure.In the FeNiMo alloy, failure in the bulk scale occured along a smooth plane at the edge of the Ni‐enrichment zone whereas in contras, for the FeCrMo alloy, failure occured withing the CrMo enriched zone adjacent to the scale‐metal interface.
