Development and Financial Analysis for the Elaboration Jominy Test Device: Conception of an Engineering Project from the Point of View Undergraduate Students

Abstract

— The proposal of the Jominy test is to analyze the hardness of certain specimens, leading to a better understanding of the heat treatments, more precisely, in the severity of the hardening heat treatment, thus contributing to the economy of finite material resources. The project is aligned with the objectives of performing this quantitative and qualitative analysis in the Jominy test project developed by undergraduate students in mechanical engineering, intended from the egress in particular as to skills and performance, in a multidisciplinary way, group work, context, design and diagnosis. The focus is to develop the knowledge about tempering, CCT curves, structure of steels and alloys, constituents such as martensite, austenite, among others, besides the application of the concepts involved in all disciplines of the semester, thus elaborating, step by step, the ideal device for Jominy tests. The main objective is to carry out a study on types of steels, heat treatments and their characteristics, constituents, tests, in order to aggregate knowledge and skills so that we can design the construction of a device for Jominy temperability tests.
