Which of the following iron carbon mixture, is the product of air cooling?
Which of the following iron-carbon mixture, is the product of air cooling?
Right Answer is:
Fine pearlite
SOLUTION
Simple heat treatment is obtained by austenitizing and air cooling to produce a fine pearlite structure.
It is established that the fine pearlite undergoes plastic deformation and ductile failure as a single structure, while the coarse pearlite exhibits a structure discontinuity upon deformation.
