The Effect of Vanadium on the Performance Properties of Al–2.3% V Alloy Manufactured by 3D Printing

— X-ray diffraction analysis, ellipsometry, and optical microscopy have been used to study aluminum alloy samples (of Al and Al–2.3% V) fabricated by 3D printing using selective laser melting. The mechanical properties of the resultant products have been compared. The strength and plastic properties of parts made from pure Al and Al–2.3% V alloys have been found to be insensitive to heat treatment. The addition of vanadium to pure Al showed that the Al–2.3% V alloy has significantly improved performance properties compared to those of primary aluminum, without affecting its initial plasticity.
