Microstructure and Metallurgical Properties of Case Carburized Steel

Abstract

In today's life, one can easily find a wide range of steel applications. These steels are broadly classified as per the composition of carbon content, alloying elements, and constitutional phases. The present investigation aims at characterizing one such steel namely case carburized steel, which is widely used in industrial machines parts such as gears, shafts, machine casings, dyes, etc. The given specimen is low carbon steel having a carbon content of 0.15%. This steel is case-carburized in a gas carburizing furnace in a carbonaceous atmosphere at a temperature of 925 degrees centigrade for five hours. The surface carbon is increased to a depth of 1mm(approximately). The sample was viewed at 100x magnification. The sample was found to consist of a major portion dominated by ferrite and mechanical testing of the same sample yielded 13-15 HRC. Thus, the present mechanical finding is well-tuned with obtained microstructural feature.
