Abstract
IN the course of an investigation into the tempering characteristics of a 12 per cent chromium steel (C 0.098, Mn 3.18, Si 3.02, Ni 4.06, Cr 12.56, Mo 0.49, V 1.09 per cent) a new phase was discovered. This phase (which we have called H-phase) could not be obtained in isolation but was always associated with M23C6. A residue extracted after tempering the steel for 50 hr. at 750° C., however, gave the maximum proportion of the new phase to M23C6. This was of the order of 2 : 1. This residue was examined in more detail by X-rays and a full chemical analysis was obtained.
