an und
gskurve The basis of the well-known suggestion according to which the inhomogeneity of
‚er eine arrangement of structure elements should be characterized by frequency histograms of the
großer intercept length of these elements has been tested by means of linear analysis of model
hr stark images of two-phase structures. The structure models evaluated were built up in a way that
gs- und they differed only with respect to inhomogeneities of arrangement but not of concentration,
chender i. e. the area fraction and the mean size of the phases present were kept constant.
The linear analysis of the model images was carried out in a completely identical way in
three. different directions. For each direction the intercept length distribution was
determined. Thus different arrangements of the structural elements could be characterized
by three intercept length distributions. The comparison of these three distribution curves
allows the conclusion that these curves show the different arrangement of structure elements
ing der with an apparently sufficient sensitivity. Therefore, the complex problem of numerical
henden characterization of arrangement homogeneity can be reduced to the simple problem of
ung zu quantitative evaluation of intercept distribution. The amount of data necessary for this
ode der characterization is connected with the problem in question.
ren. so A characterization sufficient for a special investigation can be carried out by number
ch. die matrices from which the position and the value of the extreme values of the intercept
ät, also distribution curve can be seen. Further studies have to show under which conditions this
Phasen. method which at present only has been tested with model structures can be applied to real
ls diei structures.
