Classification of Metallurgy

Metallurgical field can be divided into the following groups:
1.Processed or Extracted Metallurgy --- As the name suggests, it is the science of obtaining metals from their ores.
2.Physical metallurgy --- It is the science concerned with the physical and mechanical properties of metals.

    Physical Metallurgy can be classified as follows:
                i. Chemical composition.
               ii. Mechanical Treatment (Rolling, Forging, Extrusion, Wire Drawing, etc.)

              iii. Thermal or heat Treatment (It measures the effect of temperature and rate
                   of heating and cooling).
              iv. Testing of Metals.
                    a. Destructive Testing (Tensile testing, Fatigue Testing, Hardness Testing).
                    b. Non-destructive testing (Micro-hardness Test, Dye-Penetrant Test,
                         Magna-Flux Test, Radiographic Test, Ultrasonic Test).
               v. Metallography (Determination of metallographic structures with the help of
                   microscopes having high power).
