Segregation of Cementite from Austenite
Nature, 1932THE formation of new phases in alloys by precipitation from solid solutions has recently been studied extensively.1 These studies have given experimental evidence indicating that when a precipitate forms as plates within a crystalline grain, the crystallographic plane to which the plate lies parallel is determined, not only by the lattice structure of ...

Cementite Solidification in Cast Iron
Metallurgical and Materials Transactions B, 2014Two hypereutectic cast irons (5.01 pct Cr and 5.19 pct V) were cast and the polished surfaces of test pieces were deep-etched and analyzed via scanning electron microscopy. The results show that graphite lamellae intersect the cementite and a thin austenite film nucleates and grows on the cementite plates.

Pearlite, Ferrite, and Cementite
2015The microstructure of carbon steel is largely determined by the transformation of austenite to ferrite, cementite, and pearlite. This chapter focuses on the microstructures produced by diffusion-controlled transformations that occur at relatively low cooling rates.

Thermodynamics of cementite layer formation
Acta Materialia, 2009The formation of cementite layers upon carburization of iron is described by a thermodynamic approach assuming the establishment of an equilibrium within the carburizing gas atmosphere and between the solid and the gas. Based on that, the suppression of soot formation by adding ammonia to the gas, which has recently been reported in the literature as a
