“…The colonies of thick-lamellar pearlite are more stable. At the same time -as it was proven in earlier works [26,27] -the crystallographic orientation of the phases in these colonies (Pitch, Bagariacki) is statistically similar to that in the initial pearlite. This suggests that, locally, the spheroidization ability is determined by the interlamellar spacing, and the general description of this ability should be based on the distribution of the interlamellar spacing.…”

StabIlIty of a lamellar Structure -effect of the true Interlamellar SpacIng on the durabIlIty of a pearlIte colony Stabilność Struktury płytkowej -wpływ rzeczywiStej odległości międzypłytkowej na trwałość kolonii perlituA lamellar microstructure is, beside a granular and dispersive one, the most frequently observed microstructure in the case of metal alloys. The most well-known lamellar microstructure is pearlite, a product of a eutectoidal transformation in the Fe-Fe3C system. The lamellar morphology of pearlite -cementite and ferrite lamellae placed interchangeably within one structural unit described as a colony -is dominant. The durability of the lamellar morphology is much diversified: in the microstructure of spheroidizingly annealed samples, one can observe areas in which the cementite is thoroughly spheroidized, next to very well-preserved cementite lamellae or even whole colonies of lamellar pearlite. The mentioned situation is observed even after long annealing times. The causes of such behaviour can vary. The subject of the previous work of the authors was the effect of the orientation between the ferrite and the cementite on the stability of the lamellar morphology. This work constitutes a continuation of the mentioned paper and it concerns the effect of the true interlamellar spacing on the stability of the lamellar morphology of cementite.

“…The corresponding selected area diffraction pattern is shown in Figure 5 b, where α and θ are indexed. (As an additional comment, α and θ hold the typical crystallographic orientation relationship (Isaichev’s relationship) reported in the literature [ 20 , 21 , 22 ]). The Al and Mn concentrations in each phase (γ, α, and θ) are collected in Figure 5 c. This graph presents the partitioning trends of Mn (solid points) and Al (hollow points) across the interface for samples treated at 670 °C for 3 days.…”

Other than granular and dispersive microstructures, the lamellar microstructure is one of the most-frequently observed traits in the case of metal alloys. This work defines a geometrical model of a lamellar microstructure and presents its stereological relationships as well as our computersimulation results for this model. The applied methodology creates -at least from a theoretical point of view -a series of interesting possibilities in the field of quantitative description of this type of microstructure and examinations of the properties of the parameter estimators that quantitatively characterize it. Keywords: lamellar microstructure, pearlite, interlamellar spacing Streszczenie Mikrostruktura płytkowa to -obok ziarnistej i dyspersyjnej -jedna z najczęściej spotykanych w przypadku stopów metali. W pracy zdefiniowano geometryczny model mikrostruktury płyt-kowej, przedstawiono dla tego modelu zależności stereologiczne oraz wyniki symulacji komputerowej. Wykorzystana metodologia stwarza -przynajmniej z teoretycznego punktu widzeniaszereg nowych interesujących możliwości w zakresie ilościowego opisu tego typu mikrostruktur i badania własności estymatorów parametrów, które ją ilościowo charakteryzują.
