6. Structure and Properties
All types of materials have internal structure that essentially constitutes grains (or particles) of different phases. These particles can have different sizes and shapes, as well as different distributions
The internal structure (or microstructure) influences the mechanical, physical and even chemical properties of the material
In most cases we can modify the microstructure so as to bring about changes in the properties
