“…One study, based on neutron diffraction intensities measured over at temperatures ranging from ambient to 800 C in a eutectoid steel, claims huge deviations of the carbon concentration from the stoichiometric ratio in undeformed cementite [28]; the result is unlikely given the extensive experimental data that exist in the literature for the composition of this kind of cementite. Zhukov and co-workers have claimed, on the basis of lattice parameter measurements or metallographic observations, that the temperature from which a cast iron is quenched can alter the stoichiometry of cementite, but the results do not account for the partitioning of other solutes between the cementite and other phases [29,30].…”

“…Как дополнительный аргумент в пользу положения атомов углерода в октаэдрических позициях выдвигалось сходство возникающей при этом координации с положением атомов углерода в октаэдрических порах решётки -железа, где его растворимость достигает 9,2 ат. % [10]. С другой стороны, призматический вариант расположения атомов углерода, в отличие от октаэдрического, должен создавать сильную анизотропию свойств вдоль оси z, а многие физические и механические свойства цементита действительно обнаруживают такую анизотропию [7,[11][12][13][14].…”
