INTERACTION BETWEEN PRISMATIC AND GLISSILE DISLOCATIONS
A theoretical study is made of the interaction between moving dislocations and large point defect clusters in the form of Frank sessile loops and perfect prismatic loops. Long-range interactions are shown to be negligible. The contact interaction depends on the type and orientation of the loops relative to the glide plane and Burgers vector of the gliding dislocation. It is noted that perfect prismatic loops can interact with moving dislocations in four different ways, These cases are analyzed in detail. The interaction with a Frank sessile loop depends on its size. However, even loops possibly too small to be visible by transmission electron microscopy can form strong locking points on a moving dislocation. (auth)
