Lecture 01: Engineering Materials & Their Properties-1

This lecture covers the following concepts: Classification – Metal, non-metal; Cast Iron; Plain carbon steels; Alloy Steels; Tool steels; Non-ferrous metals – aluminium and aluminium alloys, titanium, high-temperature metals and alloys: superalloys, refractory metals, ceramics, composite materials. Self-Assessment Questions: How metal can be distinguished from the non-metals? Composite materials come under metals or non-metals? Which component differentiates cast iron from steel? Why cast iron is bad in tension? Which alloying material improves the strength and toughness?
