 Why study materials science and engineering

All engineers need to know about materials. Even the most “immaterial”, like software or system  engineering depend on the development of  new materials, which in turn alter the economics, like software-hardware trade-offs. Increasing applications of system engineering are in materials manufacturing (industrial engineering) and complex environmental systems. Innovation in engineering often means the clever use of a new material for a specific application.  For example: plastic  containers  in place of age-old metallic containers. It is well learnt lesion that engineering  disasters are frequently caused by the misuse of materials. So  it is vital that the professional engineer should know how  to select materials which best fit the demands of the design –  economic and aesthetic demands, as well as demands of strength and durability. Beforehand the designer must understand the properties of materials, and their limitations. Thus it is very important that every engineer must study and understand the concepts of  Materials Science and Engineering. This enables the engineer 

  • To select a material for a given  use  based on considerations of  cost and performance.
  • To understand the limits of materials and the change of their properties with use. 
  • To be able to create a new material that  will have some  desirable properties. 
  • To be able to use the material for different application.
