Materials Science

An ant viewed by a scanning electron microscope.

Materials science is the study of the structural and functional properties of materials. It focuses on the factors inherent within materials that influence their properties. These factors include composition, the structure of the matter within the material and the type and quantity of defects that are present. It is a multidisciplinary subject that draws upon and feeds back to the learning in just about every field of science and engineering in some way or another placing the subject in a central role to many of the activities in these related subjects.

This book is aimed at those studying materials science at the undergraduate level in university whether as their major field or as a single module of a related engineering course.
