This is an advanced text book on the microstructure and properties of materials, the first volume of a possible 3-volume set. While there are many elementary text books in materials science, there are very few advanced text books. In our graduate school courses, we rely on our own notes or some conference volumes and journal articles. One of the reasons is that there are so many different kinds of materials and each has its own microstructure property charateristics. So it is difficult for a sin
