In which of the following metalworking process, the control on grain size is maximum?

In which of the following metalworking process, the control on grain size is maximum? Correct Answer Cold-annealed-cold working

In the hot working and cold working desired nature of grain size flow can be determined, but exact control on it is difficult; but in cold-annealed-cold working, the material is first deformed then annealed to the level where the desired grain size is obtained, then again cold worked to achieve the strength.

The largest size of immobilised segment of dislocation in a Frank Read (FR) source contained in a polycrystalline material is of the order of grain size. In a metal of 10 μm grain size, the shear stress required to operate such a FR source is 100 MPa. If the grain size in the same metal is reduced to 10 μm, the shear stress required to operate such FR source would be . . . . . . . . MPa.
