It explores the way in which materials are used and the way in which production and fabrication routes influence their fitness for purpose.
The first segment of the course considers the principal properties of engineering materials that are of major importance for the practicing mechanical engineer, namely properties such as strength, toughness, stiffness, and dynamic properties. Following are major millstones:
• To help in understanding different types of materials, their structure, chemical make-up and different macroscopic properties and microscopic properties.
• To understand process of extraction, refining and production of different metals, ferrous and non-ferrous alloys.
• The major categories of engineering materials other than metals and alloys such as engineering polymers, engineering ceramics, semiconductors and composites are covered. Introduction to emerging materials such as composites and nanomaterials are included.
The next section covers the common processes available to turn these materials into actual components, and considers the process itself and the influence of the choice of processing route itself on material properties, inherent defects, failure analysis etc.
