Abstract:The deformation behaviour of binder phase regions in cemented carbides is studied using transmission electron microscopy. Stacking fault densities vary strongly up to the limit of complete transformation of the cubic into the hexagonal modification. Undissociated dislocations are rarely observed. Stacking fault intersections are limited to regions of low stacking fault density. All types of deformation defect are observed in undeformed specimens. These defects are caused by deformation resulting from the relaxation of residual hydrostatic stresses during foil preparation.
