The precipitate could be vanadium carbide from EDS (b) and selected area diffraction pattern (SAED).
The applied tungsten carbide (WC), hydroxyl-nickel (Ni), vanadium carbide (VC) and tantalum carbide (TaC) powders, and silicon carbide nanowhisker in this work were all commercially available.
In addition, Two OEMs showed new solid vanadium carbide steel alloys for screw elements.
Humphrey offers a new standard pin clamp design by applying a vanadium carbide coating to the pin.
Other topics include using natural gas to run an electrical generator for induction heating, a mathematical model for continuous annealing stainless steel strips, vanadium carbide diffusion coatings for tool and die components, and care and maintenance of quench oils.
* Microhardness of coatings of vanadium carbide is at a level of 26-28 GPa, and that of chromium carbide is 14-16 GPa.
TD (Thermal Diffusion) Center Vanadium Carbide Coating solved serious build up problems on dies for a manufacturer of athletic, school, and storage lockers.
So, Fisher turned to Arvin TD Center which coated the dies using a thermal diffusion process that metallurgically "welds" a layer of vanadium carbide to the die surface.
In these experiments, the researchers investigate the use of coatings, such as titanium nitride, boron carbide, boron nitride, chromium oxide, and vanadium carbide, to decrease die fatigue and increase process life.
For vanadium it was found that the ratio shifts from 75: 25 for a pure DLC film to 38: 62 for a sample with 48% vanadium carbide and to 20: 80 for a film with 60% vanadium carbide [40].
Specific topics include low-temperature solubility limit of cooper in iron, vanadium carbide dissolution during austenitization of a model microalloyed FeCV steel, and cleavage initiation in Ti-V-N and V-N microalloyed forging steels.
