Recrystallization, Grain Growth, and Color Etching to Design an Artistic Microstructure in Cartridge Brass (C26000)

This report details the creation of artistically engineered microstructural images for 2021 International Metallographic Contest (IMC) and Exhibit. The concept these is to utilize purposeful recrystallization grain growth make designs in microstructure. C26000 cartridge brass was material used. grains were initially grown be large through annealing then indentations added. Recrystallization induced, polished away reveal newly created designed pattern. indentation spacing load determined by testing a range loads spacings optimal parameters. best conditions follow between 80 100 μm with 1 kgf. complex AutoCAD create CSV files which input into LECO automated system (AMH55). Finally, three etchants from literature investigated, Klemm’s I, II, III, II being chosen its vibrant colors under polarized light. All investigations combined several different submission Competition (IMC).
