EFFECT OF COPPER ON PASSIVITY AND CORROSION BEHAVIOR OF FE-XC-5CU ALLOY
The correlation between corrosion behavior rate of annealed Fe-xC-5Cu alloys and their microstructure and phase composition is presented. The metallurgical analyses, including, X-Ray diffraction (XRD), the scanning electron microscopy (SEM) with energy ...

Effect of impurities on the growth and morphology of cementite nanowires [PDF]
Effects of doping on morphology of iron carbide (cementite) nanowires have been explored by first principle electronic structure calculations. We examined the role of several realistic impurities (Si, Mn, V, P and S) in the formation energies of the cementite nanowires with different sizes and morphologies.

Cementite Residual Stress Analysis in Gas-nitrided Low Alloy Steels [PDF]
This paper deals with the measurement of residual stresses in cementite after gas-nitriding of a 33CrMoV12-9 steel. During nitriding, precipitation of nanometric alloying elements nitrides and cementite at grain boundaries occurs leading to an increase ...

Kinetics of Graphitization of Cementite
Mesures dilatometriques effectuees au cours de la premiere etape du recuit de graphitisation de fontes blanches. Proposition d'une nouvelle equation cinetique a partir d'un modele suivant lequel la vitesse de graphitisation est controlee par la reaction interfaciale de dissolution de la cementite dans l ...

Effects of copper on proeutectoid cementite precipitation [PDF]
The effect of copper on proeutectoid cementite precipitation was investigated by examining the isothermal transformation characteristics of Fe-C and Fe-C-Cu alloys that had comparable carbon contents. The TTT diagrams generated for the Fe-1.43 wt pct C and the Fe-1.49 wt pct C-4.90 wt pct Cu alloys showed that the kinetics of proeutectoid cementite ...

Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

An increase in the cementite volume fraction contributed to an increase in the athermal component of strength. Strain-hardening rate increased with carbon until 0.3 wt.%C and then caused little change with a further increase in carbon, which was ...
