JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

The prime objective of the course is to make the students understand

various super alloys applied in nuclear, aerospace and space Industries.

Course Outcome

Acquiring knowledge on the course, the student will be able to select the

required super alloys for specific applications.
