Abstract :

In the era of the engineering world, new materials are developed with controlling properties during processing, to make them an excellent candidate for a suitable application. A specific hardness for metal is often a primary requisite for many applications, so monitoring the hardness of the material is crucial during manufacturing. The hardness of the material is directly influenced by several factors such as cold working, alloy composition, and amount of martensite formation. Hardenability of steel is defined as the susceptibility of the steel to hardening when quenched and is related to the extent of depth and distribution of martensite formation across a cross-section. The controlling parameters which affect the hardenability of steels are austenite grain size, carbon content, and alloy percentage. Various methods are available to measure the hardenability of the steel. Whereas the Jominy end quench test is a widely used method to measure the hardenability of steels.
