1. Properties and Structure
The properties of a material, i.e., its hardness, strength, etc. are all dependent on the chemical constituents, and that how these constituents are distributed in the body of the material, i.e., on the ‘microstructure’.
The microstructure of most materials can be modified by various techniques.
