Decomposition of Martensitic Steel Above and Below 300°C

Abstract

DURING the course of an investigation concerning metallurgical structures employing both the electron microscope and electron diffraction reflexion methods, some interesting, and perhaps important, results were obtained with a plain carbon steel. The literature dealing with the tempering of martensite at low temperatures generally assumes that the decomposition below 300° C. produces a very highly dispersed carbide phase1. It was generally concluded that the carbide particles are so small and are sufficiently deformed by stresses set up during precipitation that a satisfactory X-ray pattern could not be expected.
