The slip process depends on gliding of parts of crystal lattices along each others. Since this requires the least amount of energy, the slip occurs in directions, in which the atoms are most closely packed. Combination of planes and directions of gliding are called slip system. The main goal...
Slip and adjustment To express the slip process clearly during the prismatic transformation, Fig. 1 displays atomic positions of HCP Ti after the first and second slips of Shockley partial dislocation of 1/6 ⟨12¯10⟩ on {101¯0} planes. The interplanar spacing (√3/3a) of {101¯...
2(b) and 2(c). The dislocation nucleation and slip release part of the shear stress, but dot not release bulk stress (negative pressure). As a result, with increasing the tensile strain, plenty of energies accumulate in the system. To release energy, some voids or cracks may be ...
(b1⋅b2)where n1 and n2 are the normalized intersection lines common to the slip planes and the boundary plane, and b1 and b2 are the normalized slip directions in the pile-up and emission grains. The first expression in parentheses on the right hand side of Eqn. (1) correlates to ...
(e)‒(g) Defect mechanisms in the indentations of the prismatic and pyramidal planes. Recurrent nucleation of -type basal dislocation loops at the contact rim ‒marked “1” in (e2) and (f)‒ produces a dislocation arrangement where the constriction of leading and trailing dislocation part...
