3.  Effect of Weight Percentage of Alloying Elements on Eutectoid Temperature
 Effect of Weight Percentage of Alloying Elements on Eutectoid ‘C’ Content
 Austenite and Ferrite Stabilizers
 Effect of Weight Percentage of Alloying Elements on Expansion and
Shrinkage of Authentic Region
 Effect of Carbon %age on Martensite Temperature, Shape and Lattice
Constant
 Carbide Forming Elements
 Structure of Metal Carbides

4.  Each alloying element have a discrete effect in steel
 These effects could be,
 Solid Solution formation
 Intermetallic Compound formation
 Carbide formation
 Stabilization of a particular Phases (ferrite, austenite, martensite)
 Increase in Hardenability and Quenchability
 Alteration of Eutectoid Transformation Temperature and Carbon Contents
 Increase in Corrosion Resistance
 Increase in Machinability
 Increase in Mechanical Properties (in general)

mixture of alloying elements are present in steels
by converting austenite and ferrite stabilizing
elements as Ni and Cr equivalent respectively”
