1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose

INDUSTRYPROFILE The Indian Stainless Steel Development Association (ISSDA) is the unifying point for the growth and development of stainless steel usage in India. Founded in 1989 by leading stainless steel producers‚ it was formed with the explicit objective of diversifying the applications of stainless steel in India and increasing usage volumes in the country. At the point of formation of ISSDA‚ the main visible application in daily life was essentially household kitchenware. It currently has

Malunggay – Scientific name: Moringa oleifera Lam. Dry skin has a low level of sebum and can be prone to sensitivity. The skin has a parched look caused by its inability to retain moisture. It usually feels "tight" and uncomfortable after washing unless some type of moisturizer or skin cream is applied. Chapping and cracking are signs of extremely dry‚ dehydrated skin. Dryness is exacerbated by wind‚ extremes of temperature and air-conditioning‚ all of which cause the skin to flake‚ chap and feel

X-ray Absorption Spectroscopy X-ray absorption spectroscopy (XAS) techniques probe short- and medium-range order‚ yielding information on bond lengths‚ coordination numbers‚ local coordination geometry and the oxidation state of atoms for a wide range of solid and liquid systems. XAS experiments require an intense‚ tunable photon source only available at synchrotrons.
