INTRODUCTION TO MATERIALS SCIENCE

2021 - 2022 Fall

  • INTRODUCTION-

Some questions related to material science from everyday life...

  • Why is glass brittle, while copper is ductile? What is meant by a ductile material?
  • If we take two rods, one of Al and one of steel, why is it easier to bend the Al rod as compared to the steel rod?
  • How can I change properties like hardness, without changing the composition (say of 0.8% C steel)?
  • Why is wire of copper conducting, while piece of brick or wood non-conducting?
  • Why is glass transparent, while any typical metal is opaque?
  • Why does Iron corrode easily, while Aluminium does not (or does not seem to?!)?
  • Usually, good thermal conductors are also good electrical conductors. Why is this so? Why is diamond a good thermal conductor, but not a good electrical conductor?
  • If I pull a spring and then release the load, it ‘comes back’ to its original shape. However, a if I bend an aluminium rod, does not come back to its original shape. How can one understand these observations?

The Materials Selection Process

Goal of MSE 225 …

  • To understand the relationship between
    • Processing
    • Structure
    • Properties
    • Performance
  • To give the ability to use the right material for the right

job.

  • To help you recognize the design opportunities

offered by material selection in your own discipline
