Abstract
In highly inhomogeneous microstructures with a wide range of grain sizes the problem arises of defining an effective average grain size An original method for the estimation of effective average grain size and a parameter describing the homogeneity of microstructure are presented The coefficients of homogeneity for equiaxed and columnar microstructures are calculated The effective average grain size is calculated as a weighted sum of the average grain sizes of homogeneous grain groups
