How Does Microstructure Affect Mechanical Properties?

How Does Microstructure Affect Mechanical Properties? The microstructure of a material (such as metals, polymers, ceramics or composites) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behaviour or wear resistance. How can microstructure be related to the mechanical property of a metal? There is a very strong relationship
