Formation of eta carbide in ferrous martensite by room temperature aging
2018, Acta MaterialiaCitation Excerpt :Fig. 5a shows the unit cell of orthorhombic cementite (θ-Fe3C) projected along the <112> direction and an overlay of experimental and simulated electron diffraction patterns along the <113>, <111> and <100> martensite directions. The orientation relationship between cementite and martensite [57,58] is provided in Fig. 5a. There is no agreement between the simulated results (green) and the experimental observations, which rules out the existence of cementite in the C-rich regions.
Effect of dissolved niobium on eutectoid transformation behavior
2017, Journal of Iron and Steel Research InternationalA transmission Kikuchi diffraction study of cementite in a quenched and tempered steel
2016, Materials CharacterizationCitation Excerpt :Crystallographic analysis of orientation relationships (OR) during phase transformation is an effective tool to understand and subsequently control the microstructure and mechanical properties of engineering materials. In this regard, the crystallography of cementite precipitates in the ferrite phase of pearlitic, bainitic and tempered martensitic steels has been primarily investigated via transmission electron microscopy (TEM) [1–17]. Three crystallographic ORs between cementite (subscripted as Fe3C) and the ferrite matrix (subscripted as α) have been typically observed:
