  Objectives
   •To study the effect of the cooling rate and the amount 
    of  alloying  elements  on  the  micro  structure  and  the 
    mechanical  properties  (  Rockwell  hardness  )  of 
    medium carbon steel. 
   •To know the several techniques of heat treatment.
   What is Heat 
   Treating ?
    • Controlled  Heating And  Cooling  of  Metal  to  Change  Its 
     Properties and Performance.
     Through:
     •   Change in Microstructure
     •   Change in Chemistry or Composition
    • It  involves  the  use  of  heating,  normally  to  extreme 
     temperatures, to achieve a desired result such as hardening 
     or softening of a material. 
  Why Heat Treat?
   •  To improve Toughness
   •   To increase Hardness
   •   To increase Ductility
   •   To improve Machinability
   •   To refine Grain Structure 
   •   To remove Residual Stresses
    Heat treatment techniques 
    include 
       Case Hardening
       Tempering
       Annealing
       normalizing
       Quenching
  Case Hardening
   •Case Hardening: is the process of hardening 
   the surface of a metal, often a low carbon steel, 
   by infusing elements into the material's surface, 
   forming a thin layer of a harder alloy.
