An atom probe study of kappa carbide precipitation and The influence of silicon on -carbide precipitation in lightweight austenitic Fe-30Mn-9Al-(0.59-1.56)Si-0.9C-0.5Mo cast steels was investigated utilizing transmission electron microscopy, 3D atom-probe tomography, X-ray diffraction, ab initio calculations, and thermodynamic modeling.
Three dimensional chemical information concerning grain boundary segregation before carbide nucleation was characterized by atom probe tomography in two Ni-Cr-Fe alloys which were aged at 500 °C for 0.5 h after homogenizing treatment. B, C and Si atoms segregation at grain boundary in Alloy 690 was observed. B, C, N and P atoms segregation at grain boundary in 304 austenitic stainless steel
Carbide Precipitation - an overview ScienceDirect TopicsThe carbide precipitation can be eliminated by thermal stabilization. In this method, the steel is held at 815° to 870°C (1500 to 1600°F) for several hours. Descaling:Heat treatment causes a scale to build up on the surface of the steel. The scale is removed by several methods. Pickling is done to remove scale. The material is immersed in a bath of nitrichydrofluoric acid; the acid leaches out the scale from the
Carbide Precipitation in Fe-C-Mo-V Steels and Relationship M 4 C 3 Precipitation in Fe-C-Mo-V Steels and Relationship to Hydrogen Trapping S. Yamasaki and H. K. D. H. Bhadeshia Abstract. Strong steels suffer from embrittlement due to dissolved hydrogen, a phenomenon which can be mitigated by trapping the hydrogen at carbide particles, where it
The formation of carbide precipitates consumed a large amount of C and other alloying elements (such as Nb, V, Fe, Mo, Mn) in the matrix. When heat compression temperature increased to 1050 °C, the ne NbC precipitates dissolved in order to decrease the interfacial energy.

Modelling and characterisation of Mo2C precipitation the carbide is virtually pure Mo2C with negligible quanti-ties of iron or manganese in the metal sites. Therefore, its precipitation is modelled as if it occurs in a ternary Fe C Mosystem.). Molybdenum carbide a Cementite C Mo
Jan 16, 2021 · Carbide precipitates are effective for improving the strength and stability of high-entropy alloys. In this work, novel-designed Fe 60 Co 10 Cr 10 Ni 10 Mo 5 V 5 medium-entropy alloys (MEAs) containing 1 wt.% carbon were prepared by vacuum arc melting followed by solid solution treatment and aging. The effects of aging on the microstructure and mechanical properties of the MEAs were
