In the absence of any external stress, which one of the following statements related to the interaction of point defect and a dislocation is FALSE:

Two dislocation lines parallel to z-axis lying in the x-z plane are shown in the figure. The glide force (in Newton) exerted by the edge dislocation on the scre...

In a material, a shear stress of 100 MPa is required to bow a dislocation line between precipitates with a spacing of 0.2 µm. If the spacing between the precipi...
