Key words: Al-Si alloy, vanadium, microstructure, mechanical properties, pressure die casting 1.What is the hardness of vanadium?For the higher hardness levels of 325 HV and above, which will tend to be associated with the more rapid cooling conditions and therefore shorter thermal cycles, it can be seen that vanadium reduces the hardenability, while for the softer microstructures of 300 down to 250HV the influence of vanadium was of an increasingly positive effect.See all results for this question

What is the difference between vanadium and niobium?

It indicates some clear differences between vanadium microalloyed and niobium and niobium+vanadium microalloyed steels in that the vanadium microalloyed steels are more tolerant to increased heat input and when toughness is studied in terms of the CTOD transition temperature, interestingly an improvement in behaviour can be observed. Fig.1.See all results for this questionThe weldability of vanadium-microalloyed steels (November the effect of vanadium content on microstructure andThe current information in the literature that might aid the understanding of the 'vanadium-effect' is sparse but an early brief paper by Uchino et al and Hasegawa et al looking at mechanisms of ferrite grain refinement in normalised high niobium vanadium steels, suggests that it might arise from the effect of interphase precipitation of VN at the gamma alpha interface, preventing ferrite grain growth as The influence of vanadium-microalloying on the weldability the effect of vanadium content on microstructure andThis 'vanadium-effect' on transformed microstructure appears to be able to be active in both HAZ and weld metal microstructure development. Indeed the author has seen it in several instances where it can be contrasted with a coarse type of microstructure that typically develops in its absence.

How does vanadium affect steel hardenability?

Hart and Harrison found that the influence of vanadium was of a different sign in respect of these two factors. For hardnesses around the critical hardness level for that study (~350HV) vanadium had a decreasing effect on steel hardenability (see next section), which by itself would lead to a reduction in risk of cracking.See all results for this questionHow does vanadium affect arc welding?One study which examined the effect of vanadium by employing submerged arc welding of pipe containing 0.16%C and 1.4%Mn, showed that vanadium additions apparently reduced the risk of solidification cracking.See all results for this questionEffects of vanadium content on the carbides transformation the effect of vanadium content on microstructure and1 day ago · The effects of vanadium content on the microstructural and mechanical properties of a newly developed hot-work die steel (MPS700V) at room and elevate
