Question

Explain briefly the main strengthening methods against plastic yield at low temperature​

Answer 1

Answer:

Work hardening

Increasing the dislocation density increases the yield strength which results in a higher shear stress required to move the dislocations. This process is easily observed while working a material (in metals cold working of process).

Answer 2

Answer:

Work hardening

Increasing the dislocation density increases the yield strength which results in a higher shear stress required to move the dislocations. This process is easily observed while working a material (in metals cold working of process).
