Definition of MATERIALS SCIENCE
: the scientific study of the properties and applications of materials of construction or manufacture (as ceramics, metals, polymers, and composites)
— materials scientistnoun
First Known Use of MATERIALS SCIENCE
Study of the properties of solid materials and how those properties are determined by the material's composition and structure, both macroscopic and microscopic. Materials science grew out of solid-state physics, metallurgy, ceramics, and chemistry, since the numerous properties of materials cannot be understood within the context of any single discipline. With a basic understanding of the origins of properties, materials can be selected or designed for an enormous variety of applications, from structural steels to computer microchips. Materials science is therefore important to many engineering fields, including electronics, aerospace, telecommunications, information processing, nuclear power, and energy conversion.
