Abstract:

The proposed work intends to study the as printed solidification microstructure and mechanical properties (tensile strength, elongation at break, microhardness, etc.) of the Laser-Powder Bed Fused (L-PBFed) and Wire Arc Additively Manufactured (WAAMed IN718) parts. The said parts are to be subjected to an identical heat treatment schedule (homogenization + double stage ageing treatments). The microstructure and mechanical properties of the post-heat treated specimens are to be compared to that of the as printed as well as the conventional wrought counterparts. An attempt is also to be made to study aspects of dry sliding wear behaviour of the as printed as well as the post-heat treated parts. The potentiodynamic polarization tests are to be carried out to study the corrosion rate of the said specimens. Finally, the machinability of the additively fabricated IN718 parts is to be compared to that of the conventional wrought alloy upon executing traditional/ non-traditional machining operations.
