6 BURGER VECTORS, STACKING FAULTS - ROLE OF

increase or decrease in strength depending on dislocation density

[Solved] 6 BURGER VECTORS, STACKING FAULTS

Q.	6 BURGER VECTORS, STACKING FAULTS - ROLE OF
A.	increase in strength
B.	decrease in strength
C.	increase or decrease in strength depending on dislocation density
D.	don’t affect strength of metal
Answer» C. increase or decrease in strength depending on dislocation density
Explanation: if dislocation density is in range 1010 – 1012 m-2, it decreases the strength by easy plastic deformation. on the other hand, if it exceeds to 1016 m-2, these causes strengthening of metal by interaction to imperfections.
