Solidification of gray cast iron

Numerical modelling of thin-walled hypereutectic ductile cast iron parts

“…The presence of primary dendrites has been incorporated as an equivalent sphere representing the dendritic grains in the modelling by Chang et al [10]. 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].…”

Estudio térmico y estructural del proceso de solidificación de fundiciones de hierro con grafito laminar

“…2), disminuye la cantidad de líquido residual y los dominios constituidos por láminas de grafito tipo A incluidos en una matriz austenítica aumentan su tamaño. En el interior de éstos, las láminas de grafito continúan su crecimiento como consecuencia de la difusión del carbono a través de la austenita [10] . En la periferia de estas áreas γ+G A continúan observándose las zonas de cobertura γ+G D-temple generadas durante el enfriamiento crí-tico (Fig.…”

A Broad Literature Review of Density Measurements of Liquid Cast Iron

“…The grain size turned out to be rather large, and each grain contained several eutectic cells. Conclusions were made that austenite dendrites provide a large number of seeds for the eutectic austenite to grow on and that both hypo-and hypereutectic grey iron start to solidify by growing austenite dendrites [18]. In a later work [19], the idea was further developed that cast irons of widespread CE (carbon equivalent) values and of all graphite morphologies solidify in a similar way, i.e., that 'solidification begins with the nucleation and growth of austenite dendrites' [19] (p. 49).…”
