Abstract
Quantitative relations are shown to exist between the number-weighted and the volume-weighted grain volume distribution parameters, provided the theoretical grain volume distribution function (GVDF) is given. These relations have been derived when the GVDF is described by a gamma or a lognormal distribution function. By comparing the experimental data of austenite grains in a lowcarbon steel to those reported in literature, it is shown that the GVDF may be described more appropriately by a gamma than by a lognormal distribution function. Furthermore, a new method for calculating the GVDF from measurements made on random plane sections has been discussed and justified.
