Abstract

The structures of iron-22 per cent nickel alloys with carbon contents ranging from 0.007 to 0.14 per cent were studied by light and transmission electron microscopy. As the carbon content increased, the structures changed from random dislocation type to plate type with subcells. At the higher carbon levels, twinning was observed. A discontinuous increase in hardness with carbon content was noted which coincided with the onset of a well developed plate structure with sub-cells. Twinning appeared to have no significant effect upon hardness.
