Abstract
Elevated temperature corrosion is an important material squalor mechanism knowledgeable in boilers in power plants energy generation sectors. Metallic materials such as low carbon steels have special properties such as easy fabrication and machinability, low cost, but a solemn disadvantage of these materials is that the deterioration in properties originating from the interface with the environment and has poor corrosion resistance. The main objective of the current investigation is to achieve strengthening of SA210 Grade A1 boiler steel through microstructural refinement by Friction Stir Processing (FSP) and analyze the effect of the same on high temperature corrosion behavior. The micro-structural, hardness, tensile and corrosion resistance of the unprocessed and FSPed materials was assessed. The characterization was done by XRD and SEM/EDS analyses with an intend to suggest mechanisms behind high temperature corrosion behavior of the FSPed samples.
