Abstract

The applications of the new stereological methods such as the disector and the point—sampled intercepts have been mainly published in studies of non—space—filling particle systems with few exceptions. This paper demonstrates the feasibility of using the disector and the point—sampled intercepts as unbiased and efficient methods for size and topology evaluation of space—filling grains, with limited information on the distribution, in engineering materials. The rules of identifying and counting of grains and grain corners are given for the disector analysis. The study of the size and the topology of grains in an austenite grain growth series of microalloyed low—carbon steel samples has been used as an example.

Keywords : disector, grain growth, grain size, point—sampled intercepts, space—fi|ling grains, stereology, topology
