Abstract

Stereological estimation of second phase particle density NVby means of transmission electron microscopy (TEM) has been carried out. Modern transmission electron microscopes, with the possibility of convergent-beam electron diffraction (CBED), allow accurate measurement of specimen thickness and therefore for particle density estimation. The method of thickness measurement using CBED is described in detail.

Quantitative TEM metallography has been performed on an ODS alloy, where second phase particles (oxides) are randomly but homogeneously distributed in the matrix. For the measured specimen thickness t of 115 nm and the estimated value of mean oxide diameter of D = 2.14.10-5 mm, the estimated particle density NV was 120.00.1010 mm-3.

Keywords : CBED, ODS alloys, particle density, TEM, thickness measurements
