4. Conclusions
- The addition of vanadium has little effect on the volume fraction of the dendrite core in the IN718 alloy, but the PDS of the alloys can be significantly reduced, and the values of the No. 2 alloy and No. 3 alloy are the smallest.
- With the addition of vanadium, the porosity of the cladding layer has been significantly reduced. Analysis of the element distribution in the cladding layer shows that no segregation of the V element occurs, and the main segregated elements are Mo and Nb. The addition of vanadium will reduce the concentration of Nb in the Laves phase. It can be predicted that the difficulty of homogenization treatment of the No. 2 alloy, No. 3 alloy and No. 6 alloy is reduced compared with others.
- The Vickers hardness value of the cladding layer is measured. The addition of vanadium to IN718 alloy will increase its hardness, which also indicates that the wear resistance of the cladding layer after the addition of the vanadium element will increase. Using the Vickers hardness indentation method to measure the residual stress of the cladding layer, it is found that the addition of vanadium has a negative effect on residual stress, and that the residual stresses of the No. 2 alloy and No. 3 alloy are the largest.
- The addition of vanadium powder can significantly enhance the elongation of IN718 alloy, but it has a slightly negative effect on yield strength and tensile strength. In summary, the IN718 alloy with a vanadium content of 0.081 wt.% has a comprehensive microstructure and mechanical properties.
