INTRODUCTION Materials science, also commonly known as materials engineering, is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties.
Materials are better known as the substance or substances out of which a thing is or can be made or the substance of which a thing is made or composed; component or constituent matter. [1] Materials commonly used in today’s industry or in society are commonly encountered materials, for example, wood (timber), concrete, brick, steel, plastic, glass, rubber, aluminums, copper, paper and ceramics.
Generally, materials are classified into three types of groups; mainly metals, polymers and last but not least ceramics. Each and every type of the aforementioned group has their very own specialties, properties, structures and other characteristics. They all play an important role when it comes to selecting materials for the creation of a new equipment, device or product. Each group are observed or studied physically, mechanically, electrically, thermally, magnetically, optically and chemically.

Metals are one or more metallic elements and have a crystalline structure. They are

    Engineering materials Choice of materials for a machine element depends very much on its properties, cost, availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose…

    Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general, force is a position derivative of energy (F = - dE/dr). In other words, if there is any energy difference in space, there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:…

    Engineering Materials Week 13 18.7 How does the electron structure of an isolated atom differ from that of a solid material? For an isolated atom, there exist discrete electron energy states each state may be occupied by two electrons, which must have opposite spins. An electron band structure is found for solid materials; within each band exist closely spaced yet discrete electron states, each of which may be occupied by , two electrons, having opposite spins. 18.15 Determine the electrical conductivity…

    Engineering Materials Week 3 5.1 Briefly explain the difference between self-diffusion and interdiffusion. Self-diffusion refers to movement of atoms within a pure material; interdiffusion refers to the movement of one or more kind of atoms in a heterogeneous system. 5.7 A sheet of steel 2.5mm thick has nitrogen atmospheres on both sides at 900C and is permitted to achieve a steady-state diffusion condition. The diffusion coefficient of nitrogen in steel at 900 C is 1.2 10^-10 m^2/s, and the diffusion…
