Question

Explain how does the reduction of the grain size increase the strength of the single-phase metals?

Expert Solution

Step 1

Single phase metals are plastically deformed due to motion of dislocations in the grains. This movement of dislocations may lead to the permanent deformation of metals.

Mainly two types of deformations are slip and twinning. Slip takes place in particular slip system.

On application of barriers on the motion of dislocation decrease the deformation of metal.

Strengthening mechanism of single-phase metals are:

Grain size reduction
Strain hardening
Solid solution strengthening
