Microstructural analysis of steel:
 Steel is widely used in various kinds of practical applications. In most of the cases, steels are required to be hard enough and not to break so easily. For this purpose, materials are often designed to possess the microstructure where fine particles of other materials are dispersed throughout. 
We are studying microstructure of steels to understand how such fine particles are distributed within the material and how the steels are strengthened. By doing so, we try to find the method to obtain strongest steel ever.
