6、 Engineering ?What is Materials Science and Engineering ?Materials Science and Engineering (MSE) is an interdisciplinary field concerned with inventing new materials and devices and improving previously known materials by developing a deeper understanding of the microstructure-composition-synthesis-
7、 processing relationship.The term composition means the chemical make-up of a material. The term structure means a description of the arrangement of atoms, as seen at different levels of detail. Materials scientists and engineers not only deal with the development of materials, but also with the syn
8、thesis and processing of materials and manufacturing processes related to the production of components. The term synthesis refer to how materials are made from naturally occurring or man-made chemicals. The term processing means how materials are shaped into useful components to cause changes in the
