Materials science and engineering is a branch of science in which the different types of materials .their structure & their industrial applications.Material is the most essential thing for any industry.

Material science and engineering can be defined as the design and discovery of new materials.

The materials can have generally three states solid, liquid and gases.

The materials are classified as crystalline and non-crystalline.

In material science and engineering, different properties of materials such as metals, non-metal,ceramics, polymers, composites, glass, metal alloys, etc. are defined.

We discuss different type of ferrous and nonferrous metals with their industries as per their properties.

For example, as stainless steel has used in water applications as it has high corrosion resistance, cast iron is used for base of the machine has it has excellent compressive strength.

In crystallography, different types of crystal structuresare discussed with their remedies in detail which are most important to design a machine element.

Different type of materials processes are discussed with their limitations and advantages.

Different types of properties of materials such as mechanical, chemical, electricals also disused in details.

Conclusion:

Thus, materials science is the lifeline for living and non-living things. They are backbone of any industry. For the optimization in the industry of any engineering field, it is essential to have deep knowledge of the materials.
