The goal of this paper is to work out a procedure of revealing, as well as qualitative and quantitative evaluation of magnesium as-cast MSR-B alloy microstructure. MSR-B alloy contains additions of silver and rare earth elements. It is characterized by high tensile strength and good creep resistance. These alloys are intended for elements working at higher temperatures (up to 250 oC). Significant stress was put on preparation of metallographic specimens and good conditions of image acquisition for light and scanning microscope. On the basis of testing six etching reagents it was found that the best results from the quality as well as quantity metalography point of view were given by reagent composed of 85% glycol and 15% nitric acid. Analysis of chemical and phase composition of the examinated alloy was performed on samples etched using this reagent. Procedures allowing for significant acceleration and simplification of estimation of quantitative description of [alpha] phase's grains and eutectic precipitation were elaborated.
