Why practical assessments of dislocation density by XRD ignores the texture which apparently affects the result?

As one can read in numerous papers on this matter, the dislocation density is derived from the dependence of peak broadening on the diffraction angle, that is, on considered reflections. Thus, to...

There is study by Rinn et al. (1996) on the comparison between drill resistance and wood density.

Rinn F., Schweingruber F.H., Schar E. 1996. RESISTOGRAPH and X-ray density charts of wood. Comparative evaluation of drill resistance profiles and X-ray density charts of different wood species. Holzforschung. 50: 303:311

René K.W.M. Klaassen

We did at SHR Wageningen the Netherlands a study on the relation between the wood density of meranti and the drilling resistance. The results are not published yet but we find such a high relationship that it was possible to predict the wood density on the basis of a resistance profile.

Nicola Macchioni

Many years ago we did the same, measuring on Norway spruce small samples. The correlations were always very high.

In any case I have to add that accurate results can be obtained only at laboratry level, on small samples. If the drilling conditions are not "perfect" and regular Resi and similar tools cannot be considered as measuring systems. On site drillings cannot be considered as real density profiles.
