a
The simultaneous breaking of all bonds along a crystallographic plane
b
The step-by-step movement of point defects
c
The simultaneous breaking of all bonds along a grain boundary
d
The step-by-step movement of linear imperfections
Homework Answers
Mechanism of plastic deformation in the metals is the breaking
of all bonds in the metallic structure simultaneously along the
crystallographic plane.
Point defects does not move in the plastic deformation of
metals.
Breaking of all bonds is not along the grain boundary but it is
along the crystallographic plane.
Linear imperfection does not move step by step in the plastic
deformation of metals.
Thus, (a) is the correct answer.
Simultaneous breaking of all bonds along the crystallographic plane.
