JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective:

This Laboratory course is designed to make the student understand and demonstrate the various types of heat treatment processes, process variables and surface hardening treatments for ferrous and non-ferrous metals and alloys.

Course Outcome

The student would gain hands on experience to define heat treatment

cycles for ferrous and non-ferrous metals and alloys with proper understanding of different heat treatment process variables.
