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

ALCOHOLS Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. For the purposes of UK A level‚ we will only look at compounds containing one -OH group. For example: Primary alcohols In a primary (1°) alcohol‚ the carbon which carries the -OH group is only attached to one alkyl group Some examples of primary alcohols include: Secondary alcohols In a secondary (2°) alcohol‚ the carbon with the -OH group attached is joined directly to

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
