In microalloyed steel industrial candidate for application to parts of automobiles we investigated strengthening mechanism by vanadium carbide (VC) precipitation in the pearlite The specimens containing 0 1–0 65% carbon (C) and 0–0 4% vanadium (V) were quenched from 1200 to 650–550C and kept at this temperature The more V and the
IBC's VCTDH coating is performed using a hot process (1800-1900 F) that combines carbon from the tool surface with vanadium to grow a vanadium carbide layer that is metallurgically bonded to the substrate This method of thermally diffusing a vanadium carbide layer onto the surface creates an incredible bond far stronger than any deposited

In the present work commercial Vanadis 6 tool steel was selected as a substrate for deposition of vanadium carbide by TRD using the pack cementation method The growth and microstructure of vanadium carbide layers are investigated Experimental Vanadis 6 is a chromium-molybdenum-vanadium alloyed powder metallurgical tool steel which
It is reported that the carbide layer is formed on the  steel surface by dipping the steel part in a molten salt bath where vanadium is added to as an oxide The layer of vanadium carbide formed on the steel part is in the form of VC0 88 C Chemical Analysis of Alloy Layer The analysis of chemical composition across the alloy layer
The amount of vanadium in steel is no more than 0 5% except for high-speed tool steel Vanadium can refine grain in ordinary low carbon alloy steel improve the strength and yield ratio and low-temperature property of steel after the normal fire and improve the welding property of steel W is a refractory carbide in high-quality spring
Vanadium microalloying additions are common in medium carbon ferrite-pearlite steel shafts The increased load capacity provided by vanadium carbonitride precipitation is beneficial in many applications Induction hardening can further increase the surface strength of a component however the implications of the vanadium carbonitride
The art of producing the famous 16-18th century Damascus steel blades found in many museums was lost long ago Recently however research has established strong evidence supporting the theory that the distinct surface patterns on these blades result from a carbide-banding phenomenon produced by the microsegregation of minor amounts of carbide-forming
18 07 2013The mechanical properties are also sensitive to the volume fraction of carbide precipitate which has been studied by changing the vanadium and carbon contents of the alloys The dispersion can be further influenced by addition of alloying elements e g manganese which alters the kinetics of
