Materials engineers
What do materials engineers do?
Materials engineers design, produce and evaluate materials and their use.

Materials engineers are experts on materials – how they are made, how and why materials are useful, and how materials can be made better. Materials engineers are concerned with every stage of a material’s lifecycle from mining to recycling. They design new materials, devise processes for making materials and disposing of them, they select the best material for a particular job, monitor its performance and figure out why a material failed.

What is Materials Engineering?
Materials engineering is all around us. From buildings to transportation to the electronic devices we use every day, the materials involved have been designed or chosen carefully for the task.

Materials have an important role in every field of engineering. The materials we use and how we make them can determine the function, feasibility, environmental impact and many other aspects of things we create.

What is Materials Technology?
Materials technology is a relatively comprehensive discipline that begins with the production of goods from raw materials to processing of materials into the shapes and forms needed for specific applications.

Materials - metals, plastics and ceramics - typically have completely different properties, which means that the technologies involved in their production are fundamentally different. Materials technology is a constantly evolving discipline, and new materials with interesting properties lead to new applications. For example, the combination of different materials into composites gives rise to entirely new material properties. Materials Science is closely related to materials technology. Materials Science is a multidisciplinary field that connects material properties to the material's chemical composition, micro-structure and crystal structure.
