Abstract
Quantitative evaluation rather than visual inspection of HRTEM images provides objective, reproducible, and very accurate information on the atomistic structure of internal interfaces. To demonstrate the power of such 'quantitative HRTEM' this paper presents analyses of particular grain boundary structures: Domain boundaries in PbTiO3, and 'incoherent' twin boundaries in Cu and NiAl. In each case the atomistic structure has been determined not only with high precision but also within well-defined error limits. Thus, the experimental results provide sensitive tests for physical theories and model structures obtained by computer simulation.
