Q.

Dislocation density can vary from            

A. 105 – 1012 cm-2
B. 105 – 1012 m-2
C. 108 – 1010 cm-2
D. 106 – 1010 cm-2
Answer» A. 105 – 1012 cm-2
Explanation: dislocation density varies in metals from 105 cm-2 (in carefully solidified metal) to 1012 cm-2 (in heavily deformed metal). it depends on various parameters as degree of deformation, temperature etc.
