Materials engineering (correct answers)
Materials Science and Engineering correct answers is an interdisciplinary field that
studies and manipulates the composition and structure of materials across length scales
to control materials properties through synthesis and processing
Composition correct answers means the chemical make-up of a material
Structure correct answers means the arrangement of atoms or ions in the material
Microstructure correct answers Structure at a microscopic scale
Synthesis correct answers refers to how materials are made from naturally-occurring or
man-made chemicals
Processes correct answers means how materials are shaped into useful components to
cause changes in the properties of different materials
Materials Science correct answers the emphasis is on the
underlying relationships between synthesis and processing, structure, and properties of
materials
Materials Engineering correct answers the focus is on how to translate or transform
materials into useful devices or structures
