Texture in Cold Rolled and Magnetically Aged Fe–Mo–Ni–C Alloys

Abstract

The texture change due to the increase of cold rolling reduction in Fe-Mo-Ni-C alloys is described. Orientation Distribution Functions (ODF) for samples cold rolled 80%, 90%, 97% and 99% are shown and discussed. Below 90% cold rolling reduction, the texture in these alloys is similar to that of cold rolled low carbon steels. Above 90% cold rolling reduction, a decrease in the component {001}〈110〉 is observed and the texture becomes weaker probably due to the development of shear bands. Magnetic age-annealing at 610°C for 1 h does not recrystallize completely these alloys. Samples cold rolled above 90% (97% and 99%) present an increase in the {001}〈110〉 component, this being responsible for a corresponding increase in the magnetic anisotropy of these alloys.
