Q748.
Pick out the wrong statement.

a.

Both annealing and normalising release the internal stresses of the material besides improving the mechanical properties.

b.

Low carbon steel does not respond to the heat treatment for hardening of the material, hence it is subjected to case hardening or surface hardening processes like cyniding, carburising, nitriding etc., which produces high carbon outer layers resulting in increase of surface hardness.

c.

Induction hardening and flame hardening techniques are also used for surface hardening.

d.

Martempering of a material is a hardening process.

Discuss
Answer: (c).Induction hardening and flame hardening techniques are also used for surface hardening.
