Heat treatment is an important topic under Engineering materials and refers to the process of heating the metals, holding them at a specific temperature, and then cooling them down. This process leads to changes in the mechanical properties of a metal. Heat treatment for computer science and mechanical engineering is not only important for the GATE exam, but also to prepare for IES (ESE), UPES, BITSAT, ISRO, and other mechanical engineering exams. This article mentions important heat treatment topics for GATE ME, heat treatment GATE notes, heat treatment GATE syllabus, and heat treatment study material for GATE ME.

Important Heat treatment Topics for GATE ME

Listed below are common heat treatment methods:




In this method, the metal is heated past the upper critical temperature and then slowly cooled down.


It is a heat treatment method used to alleviate internal stresses caused due to casting, welding, or quenching.


Hardening is the commonest of heat treatment processes. It is used to boost the hardness of a metal. Sometimes only the surface of a metal is hardened.


Aging is also known as precipitation hardening. It is a method usually used to boost the yield strength of metals.
