“…We want to know why the microstructure turned colorful after etching. Recently, some coloring mechanisms of color etchants for alloys have been studied [3][4][5][6][7][8][9][10][11][12]. In those studies, the surface morphology has been proved to be the key factor that produces the color after etching.…”

“…Austenite dendrites can, however, also be present in hypereutectic ductile iron [11][12][13]. The presence of austenite dendrites seems to be even more pronounced in thin walled castings [14]. While the growth of flake graphite iron is shell-like, the growth of ductile iron is equiaxed, increasing the risk of shrinkage porosities [15].…”

“…The aim of the present work is therefore to verify the numerical model from ref [16] with experimental results showing the presence of off-eutectic austenite dendrites in hypereutectic ductile cast iron. As the austenite dendrites seem to be more pronounced in thin walled castings than in thicker castings [14], thin walled castings will be the main focus of the paper. In order to improve the thermal analysis the solidification model is implemented in a transient 1D description, enabling an investigation of the effect of the heat transfer coefficient and the thermal gradients in both casting and mould on the evolution of microstructure in hypereutectic thin walled castings.…”

“…Numerous studies have been published on thin wall ductile iron, particularly on the solidification morphologies, 8) microstructure characterization, 3,9,10) mechanical properties, 11,12) carbide formation factors, 1,13,14) production, 15,16) mould filling 17,18) and thermal analysis. 19) Moreover, various experimental relationships have been developed between the chemical composition, 10,14,16) pouring temperature, 14) spheroidization and inoculation practice, 14,15) casting geometry, 20) plate thickness, 2,10,14) and mould materials.…”
