Do Dislocations Affect Ductility?

In contrast to the above planar defects, the strength of metallic materials monotonically increases with dislocation density according to the well-known Taylor hardening law (9). The problem is that ductility tends to decrease as the number of dislocations increase.

What factors affect ductility?

Factors that Affect Ductility of Metals:

Ductility is affected by intrinsic factors like composition, grain size, cell structure etc., as well as by external factors like hydrostatic pressure, temperature, plastic deformation already suffered etc.

What is the effect of dislocations?

Dislocations can be very painful and cause the affected joint area to be unsteady or immobile (unable to move). They can also strain or tear the surrounding muscles, nerves, and tendons (tissue that connects the bones at a joint). You should seek medical treatment for a dislocation.
