    Direct observation of grain-boundary dislocations in the FeCo alloy

    A unified dislocation theory of grain boundaries proposed earlier for simple cubic crystals has been extended to include the case of ordered and disordered body-centred-cubic structures. Pure symmetric and asy...

    Direct observation of grain-boundary dislocations in the FeCo alloy

    An extensive transmission electron microscopy study has been made of the structure of high and low angle grain boundaries in both ordered and disordered FeCo alloys which were electrochemically thinned from th...

    Twist boundaries in ordered alloys

    A detailed analysis has been made of the equilibrium configuration of some of the simpler types of twist boundaries anticipated in ordered alloys. Similar to the case of tilt boundaries, it is found that the e...

    Dislocation behavior at tilt boundaries of infinite extent

    A detailed theoretical analysis has been made of the stress fields which arise from the motion of glide dislocations across a symmetric tilt boundary. These stress fields are long range and result from the for...
