| Abstract Scope |
Additive friction stir deposition (AFSD) has recently attracted significant interests from the aerospace and defense industries due to its advantages over the conventional 3D printing techniques. Despite the recent advancements in AFSD of different metallic alloys, the deposition of harder and stronger materials is still challenging. Aluminum 7075 is one of such alloys with a high strength comparable to many steel alloys. In this study, AFSD was utilized to 3D print Al 7075 and the microstructural and mechanical properties of the as-deposited parts were studied. The average microhardness reduced from 177 HV for the feedstock material to 80.4 HV for the fabricated parts along the building direction. Similar to the microhardness, tensile strength of the 3D printed parts experienced a decrease from 586 to 306 MPa. X-ray diffraction analysis and energy dispersive X-ray spectroscopy indicated formation of large and detectable precipitates in the as-deposited parts compared to the raw materials. |
