Materials Science and Engineering INTRODUCTION Materials Science and Engineering The Materials Selection Process Application Properties Materials Processing Why do we study materials in an engineering curriculum Engineers facing design or production problems are going to be involved with material selection, which requires basic understanding about the materials science and engineering. Civil engineers-structure of a building Mechanical engineers-design and production of transmission gears Chemical engineers-an oil refinery component Electrical engineers-an integrated circuit chip Environmental engineers-liner for landfilling site Industrial engineers-product cost including expenses during fabrication as well as raw material and quality Structure Property Mechanical properties Electrical properties Thermal properties Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero Thermal conduction is the transfer of heat within one material or between materials in contact. Thermal convection is the transfer of heat from one place to another by the movement of fluids. Magnetic properties The response of the materials to an external magnetic field varies which is measured in terms of their magnetization (strong or weak) Optical properties  Metallic Materials Metals are composed of one or more metallic elements such as Iron, Copper and Aluminum However, pure metals are used so rarely due to its low mechanical and physical properties Therefore, the combination of pure metals together are called alloys Alloys are used to increase the mechanical properties of the metals  Metals and alloys Chromium is added to steel to Tungsten, cobalt and Vanadium are added to improve corrosion resistance steel to improve high temperature mechanical (stainless steel) properties. Non-Metallic Materials  Report Determine different types of application for Metallic and Non- Metallic applications
