Atlas of Microstructures Aids Analysis of Aluminum Castings
Help the reader who has an image of an alloy microstructure identify the examined alloy in a gallery of standard casting aluminum-silicon alloys.
Help the reader to identify the typical microstructure of an alloy based on its estimated cooling rate.
The Atlas was composed considering the cast part as a complex construction of crystallites, described in the context of particular technological conditions and initial chemical composition. Chapters I and II discuss the characteristics of the main phase constituents: α-Al solid solution and silicon crystals (Ch. I), and intermetallic phases (Ch. II). Chapter III presents an atlas of the microstructures of aluminum-silicon cast parts, designated according to standard PN EN 1706, taking into account its counterparts in ASTM-standards. Chapter IV presents the metallographic procedure of the visual identification of the alloy phase constituents.
