Review on Recent Trends & Optimisation in Heat Treatment

Abstract

Progress and productivity are the keys to survival, and green manufacturing is a prime source for innovation. In the past few decades a slow rate of development in heat treatment has been done, due to its ignorance and poor understandability. Recently market has started eyeing on heat treatment and surface engineering as the most vital departments were lot of research and development is to be done because of the continuous demand of energy efficient, environmental friendly, optimum cost process. Heat treatment and surface engineering are the key technologies to enhance effective use of materials applied for automobiles, aerospace and weapons. After understanding, such a vital role of heat treatment many advanced steps like vacuum heat treating, development in quenching media , laser heat treating, electromagnetic processing, intensive quenching have been taken which has resulted in 30% increase in case depth, 25-30% reduction in process time, 30% reduction in energy consumption and purely environmental friendly process. This paper presents a short overview of new trends of heat treatment and process optimisation with its future technical possibilities. Keywords:
