Which statement is false? |
A. | plastic deformation decreases dislocation density. |
B. | strain hardening is the increase of dislocation density with plastic deformation. |
C. | slip plane is the crystallographic plane of dislocation motion. |
D. | dislocation can change its plane of motion by climb on high temperatures. |
Answer» A. plastic deformation decreases dislocation density. | |
Explanation: plastic deformation increases the dislocation density. plastic deformation causes generation of dislocations due to the frank-read source. all other statements are correct. |
