Investigation of the effect of added vanadium element in casting of Etial 177 aluminum alloys

In the aluminum casting industry, the addition of vanadium (V) to the aluminum alloy is important in order to increase fluidity and mechanical properties. In this context, in this study, vanadium element was added to Etial 177 alloy and its effects on liquid metal cleanliness, fluidity and mechanical properties were examined through experimental studies. In the casting process, the permanent mold casting method was used. In the experiments, the effects of adding different amounts of V to the Etial 177 standard aluminum alloy on the properties of the alloy were examined. In the study, ETİAL 177 reference samples were produced with the V addition amount to be 0.03%, 0.05% and 0.1% V, and in order to detect the difference in the sample casting processes. Solidification under vacuum, K-mold mold, mechanical test mold, 4-channel flow mold with varying cross sections and spiral flow mold were used in the castings. In the samples taken from the castings of the test alloys, it was determined that VAK samples had pores below 0.5% in density measurements and K values below 1 in K molds. The elongation amount, which was 2.76% in ETIAL 177 casting without addition, increased with increasing V amount and reached a maximum value of 7.61% with 1% V addition. It was observed that the tensile stress values increased up to 137 MPa in ETİAL 177 castings without addition, 159 MPa with 0.03% V addition, 168 MPa with 0.05% V addition and 185 MPa in castings with 0.1% V addition.
