AMIE Exam Lectures- Materials Science | Metal Alloys | Ferrous Alloys & Non Ferrous Alloys | 11.1

Introduction - :
Previous Lecture - Different Heat Treatment Processes
Present Lecture - Metal Alloys

Metal Alloys - Divided into two basic categories
- Ferrous Alloys
- Non Ferrous Alloys

Ferrous Alloys is further subdivided into steel and cast iron.and further into many categories as mentioned in slide.

Low carbon steel - :
- Not responsive to heat treatment
- Low strength
- very good ductility and toughness

High Strength Low Alloy - :
- Total alloy concentration till 10 %
- Stronger than plain alloy
- Better resistance to corrosion than plain steel

Medium  Carbon Steel - :
- Can be heat treated
- Tempered martensite microstructured used
- Stronger than plain iron

Stainless Steel - :
- Highly resistence to corrosion

High Carbon Steel - :
- Used in Hardening and tempered condition
- Hardest, Strongest but least ductile of carbon steel
