The following creep map is plotted with homologous stress and temperature, as shown in the region. The Dislocation glide region is shown by region ________

The following creep map is plotted with homologous stress and temperature, as shown in the region. The Dislocation glide region is shown by region ________ Correct Answer IV

The dislocation glide is pure mechanical deformation of the material; there is minimal diffusion associated with dislocation glide. Hence this region will have a very high-stress value and range in the entire temperature range.

Shear stress required to bend a dislocation of radius R and burger vector b is P. What will be shear stress needed to turn a dislocation of radius 2R and burger’s vector 2b to bend the dislocation?
The interaction of screw dislocation and edge dislocation produces ______ on the edge dislocation and _______ on the screw dislocation.
The Burgers vector b is the vector which defines the magnitude and direction of slip. For a pure edge dislocation, the Burgers vector is perpendicular to the dislocation line, while for a pure screw dislocation, the Burgers vector is parallel to the dislocation line.
