.... Figure 9.5 shows how deformation twins reduce the free mean path for dislocation glide, causing the high strain-hardening rate observed in TWIP steels. Twinning is important in hexagonal crystals because dislocation slip can only occur on one plane, the (0001) plane. If this plane is normal...

... in Fig. 2.12 , an applied stress will be reached when the shear stress, resolved onto a slip plane in a slip direction, attains a critical value so that dislocations on that slip plane slip or glide. If the normal, n , of the slip plane lies at an angle, ϕ, to the tensile axis, its area will be A /cos...

Having climbed, the dislocation proceeds along the new slip plane until it encounters another resistant obstacle, whereupon it climbs (or descends) to another parallel plane and the process repeats. Since dislocation motion depends on both dislocation glide and climb, the term climb...

... vector, b , is parallel to both the axis of the dislocation, t , and the displacement vector, u ; that is, ( b ‖ t ‖ u ). If dislocations could only move by gliding on a single slip plane, they would soon be impeded by obstacles and their motion would be restrained. However, screw dislocations...

The hard martensite islands obstruct dislocation glide and cause an increase in the stress level. The soft ferrite phase...
