Sintered Steels - Low Alloy Steels: Nitrogen Alloying of PM Steels: Processing and Properties

Abstract
A process has been developed to introduce nitrogen as a bulk alloying element in low alloy PM steels. The use of nitrogen to replace carbon as an alloying element to develop Fe-N martensite instead of Fe-C martensite is of interest since it has been suggested that, in ingot steels, at a given strength level, Fe-N martensite exhibits enhanced ductility, compared with Fe-C martensite; nitrogen promotes the formation of tough lath at the expense of brittle plate martensite. Sintering and post sinter processing are detailed in relation to attendant microstructures and mechanical properties of PM Fe-N and equivalent Fe-C alloys, in particular strength and ductility. The hardenability of Fe-N, Fe-C and Fe-N-C alloys was also determined utilizing the jominy end quench test. In 4100 alloys the hardenability of Fe-C was superior to that of Fe-N and Fe-C-N.
