N2 - Temperature dependence of the apparent antiphase boundary (APB) energy on cube planes is studied using weak-beam determination of dissociation distances ofsuperdislocations originating from deformation at 20,650 and 850°C. It is difficultto assess how closely the observed dependence applies to the true cube ABP energybecause of the uncertainty associated with lattice resistance to the motion ofsuperpartials. It is estimated that the true energy of conservative APB on {001} isliable to decrease with temperature by as much as 30% between room temperatureand 850°C. © 1989 Taylor & Francis Group, LLC.
