Different class of materials are designed for specific applications. Materials are tuned to the required physical, chemical, mechanical, and electrical properties, etc for these applications. However, interactions of the material with the atmosphere determine its life. Such environmental interactions and economic considerations determine the development and use of a given material for the specific environment. The research on the development of materials with novel, advanced properties have been driven by this need. However, at the same time, mitigation strategies have also been developed to prolong life. In this presentation, a brief overview of research development in understanding the degradation modes of metallic materials, its development, and novel mitigation strategies will be discussed. The new perspective, challenges, and the future scope in material degradation and its mitigation, in the light of the metallic material, will be discussed.
