| Abstract Scope |
Al-Cu alloys are largely used in the automotive and aerospace area, but with the advance of technology new alloys are necessary. Sc additions show an effect to improve the performance of Al-Cu alloys. This work shows the characterization of Al-4.5wt%Cu-04wt.%Sc alloy with and without TiB2 addition in the hybrid investment casting of lattices process. The experimental proceeding consists of PLA 3D printer lattice attached to the rubber base using polymer clay, pouring the plastic cast ceramic slurry into the flask with print inside, burnout cycle to eliminate wax/polymer in the mold, pouring the alloy in a preheat mold attached with an applied vacuum. Microstructure and microhardness were observed. This work aims to also explore the effect on microstructure and hardness of TiB2 as the refined grainer for Al-4.5wt%Cu-04wt.%Sc alloy. |
