7. Introduction to Heat Treatment
 Heat treatment operations are intended to modify the characteristics of metallic
materials on surface or in depth.
Influences & Effects
• Hardness • Tribological properties (friction)
• Toughness • Corrosion resistance
• Breaking strength • Magnetic properties
• Resilience • Dimensional stability
• Ductility • Yied strength
 A heat treatment operation is to subject the material to a thermal cycle including :
 Heating at required speed.
 Holding at temperature.
 Cooling to a certain speed.
