“…A larger austenite lattice parameter is observed in the slow-cooled specimen (Figure 5), which is consistent with the extended time allowed for carbon to partition into the austenite during martensitic transformation [27]. measured lattice parameter of MC in this work is comparable to some literature values [30][31][32], whilst there are slight differences (but less than 0.6%) when compared to other data [7]. There is no evidence from the obtained synchrotron XRD spectra that the monoclinic V 6 C 5 [13] is formed.…”

“…The lattice parameters of the molybdenum-rich carbides (MC) are very close to the reported values [28,29].

There is no evidence from the obtained synchrotron XRD spectra that the monoclinic VC [13] is formed.…”

A novel, low-alloy steel has been designed for use in the oil and gas industry. Its high strength and hydrogen trapping potential are derived from a martensitic microstructure containing a dispersion of fine vanadium-molybdenum alloy carbides that evolve during tempering. In this second paper, the effect of quench rate from austenitisation and tempering conditions are investigated with respect to the microstructure. The alloy loses its tempering resistance following slow-cooling from austenitisation as a result of MC precipitation, leading to vanadium depletion and significant M 2 C coarsening. This is predicted using computer simulation and confirmed by high energy X-ray diffraction, combined with electron microscopy.
