Hydrogen trapping in bearing steels: mechanisms and alloy design
… and ductile microstructure, and (2) nano-sized vanadium carbide precipitates acting as hydrogen traps. A novel technique is proposed to visualise the migration of hydrogen to indentation-induced cracks. The observations employing this technique strongly suggest that hydrogen enhanced localised …

The fracture toughness of ultrafine WC-Co Alloys
… toughness behaviour of a series of cemented carbides having carbide grain sizes between 0.35f.Lm and 4f.Lm, cobalt contents ranging from 6 to 15wt%, and vanadium carbide contents from 0 to 0.8wt%. A series of twenty-four ultrafine WC-Co alloys were sintered from powders produced through three …

Impacts of Vanadium and Coke Deposition on CO2 Gasification of Nickel Catalysts Supported on Activated Carbon from Petroleum Coke
… °C and/or impregnated with ~3.5 and 8.5 wt% vanadium, which is typically deposited during hydrodemetalization (HDM) of heavy oil. The gasification rates of all samples were 30-400 times greater than the rate of gasification of uncatalyzed (i.e., no metal) AC. Rate profiles as a function of …

The impact toughness of iron manganese alloys.
… by low temperature ageing has shown that vanadium carbide precipitation produces a significant reduction in grain size upon re-austenitisation due to particle pinning of grain boundaries.

Stress relief cracking in creep resisting low alloy ferritic steels.
… was felt that certain Cr-Mo-V steels containing vanadium carbide should be particularly susceptible to this mode of failure, since V4 C3 is well known to confer very good creep strengthening in these low alloy steels. As a result of this work, it has been established that the above view is both …

Consolidation of WC-Co nanocomposites synthesised by mechanical alloying
… on the mechanical properties of a tungsten carbide-cobalt (WC-Co) hardmetal, based on 10wt% Co, has been established. The effects of high-energy milling for 30, 60, 180 and 300 min and the interrelation between milling time and powder properties, and the resultant effects on the mechanical …
