Dislocations and Strengthening Mechanisms Introduction With the knowledge of the nature of dislocations and the role they play in the plastic deformation process, we are able to understand the underlying mechanisms of the techniques that are used to strengthen . Mechanism of strengthening is different from other methods. Higher modulus fibers carry load, ductile matrix distributes load to fibers. Interface between matrix and fibers thus plays an important role. Strengthening analysis involves application of continuum, not dislocation concepts as in other methods of strengthening.

Mechanism of strengthening is different from other methods. Higher modulus fibers carry load, ductile matrix distributes load to fibers. Interface between matrix and fibers thus plays an important role. Strengthening analysis involves application of continuum, not dislocation concepts as in other methods of strengthening. and strength of the a ductile material as a result of plastic deformation at temperatures far below its melting point. • Indeed, plastic deformation leads to the multiplication of dislocations, which strain fields start to interact more “closely”, hindering the dislocations motion. 3: Strain Hardening Dislocation tangles produced by. Material Strengthening Mechanisms Academic Resource Center. Agenda •Definition of strengthening •Strengthening mechanisms Strengthening •The ability of a metal to deform plastically depends on the ability of dislocations to move. •Hardness and strength are related to how easily a metal plastically deforms, so, by reducing.
