A CASE STUDY ON NI BASED SUPER ALLOYS AGEING FOR IMPROVEMENT OF ITS PROPERTIES

Abstract: Few studies have been done on the investigation of aging process of Ni based super alloys. There is a need of more investigation to control the above process by using aging at different temperature for different durations of time. It is also found from the study that microstructure, physical and mechanical properties of material depend on temperature, time and quenching medium. In the present work, effect has been made to study the methods of improving the hardness, strength and other properties of the super alloy.

Keywords: Super-alloys, Carbon based super-alloys, ageing and heat treatment, etc.
