Material Science

General Overview

Materials science is a field of engineering concerned with the design and discovery of new materials and its ability to be implemented into a current product or system. It is an interdisciplinary discipline combining the physics and chemistry of matter along with engineering application.

 

Material scientists investigate the strengths and properties of materials by performing failure analysis through both computational and physical tests. They study the relationships between material structures and properties, developing new processes to manufacture these materials and utilise these processes to achieve a desirable and usable product. New materials can have functions in many industries including biomedicine, civil, automotive, aerospace and electrical engineering sectors. Material science takes materials back to fundamental principles to investigate its atomic, microscopic and macroscopic structure, understanding how these structures interact when applied under specific loads in specific conditions.

All engineers should have a fundamental knowledge of material science to be able to assist with the design, manufacturing, maintenance and containment of materials in a safe manner.

 

Materials science is a relatively new discipline of engineering which became recognised in the 1940s. Research in the field has lead to breakthroughs in technology such as lightweight composite manufacture and nano materials. Today society is heavily dependent on lightweight materials for lighter and faster vehicles and optical fibers for telecommunications. Nanotechnology, medical technologies and lightweight materials are still areas of copious research.
