Non Destructive Metallographic Technique Used in Indian Space Programme

Metallography technique is used as an important tool in designing and development of materials. The technique is destructive and hence has its own limitations. Non destructive metallography emerged as a solution for its limitations. The microstructure of the component in the field/service can be replicated and observed under microscope. In the recent past, this technique has drawn the attention of quality control personals due to its non destructive nature. This paper explains the use of nondestructive metallography technique for Ti-6Al-4V alloy domes and low carbon steel static test bed exposed to high temperature.
