Option iv. slip causes plastic deformation is the wrong statement. Slip is a key factor in the deformation of metals. It entails the movement of crystal blocks over one another along various crystallographic planes that we refer to as slip planes. It occurs in separate atomic spacing multiples.
After deformation, the crystal's orientation above and below the slip plane is the same as it was before.
It happens over a number of milliseconds.
It takes place over a large plane.
There are slip lines whether the number is even or odd.
Slip occurs when the critical resolved shear stress, also known as the shearing stress threshold, is reached on the slip plane in the slip direction.
