Introduction to materials science and engineering

Materials have always been an integral part of human culture and civilization. For example, we designate periods in the past as the stone. Bronze, and ages. Today’s advanced technologies rely on sophisticated materials. All of them use devices, products, and systems that consist of materials. The engineer’s expertise lies in adapting  mantillas and energy to society’s needs.

The theme of this text is that the properties of materials depend their menial structure. In turn the properties influence the performance of a material. Both during manufacture and during service. To change the performance of a material, we must motifs its  internal structure. Conversely, if service conditions alter a material structure, the engineer must anticipate that changes will occur in properties and performance.

Materials and civilization

Among the various attributes of the human species is the ability to make things. Course all abject tools components, and engineering systems require the use of materials to meet their purposes. The role of materials has been sufficiently portent in the progress of civilization that the anthropologists and histamines identified early cultures by the most significant material used then. Consider the stone the bronze, and the iron ages of the past. These days however we are not limited to one predominant material. Rather, we have a multitude of sophist dictated materials. Plastics, silicon. Titanium. High technology ceramics optical fibers, and so no fig 1.1 we can refer to our modern society as the age technology.
