Main Types of Industrial Material Metals and Alloys Ceramics Polymeric Materials Composites
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
