摘要：
Shear Assisted Processing and Extrusion (ShAPE) is presented as a new manufacturing technology for converting aluminum scrap directly into extruded products. In this work, a porthole die configuration is integrated within the rotating ShAPE process to extrude circular, square, trapezoidal, and two-cell trapezoidal profiles from aluminum alloy 6063 industrial scrap. Microstructural characterization is pre-sented for a trapezoidal profile having an average grain size of 6.7 lm in the as-extruded condition. Round tubes achieved yield strength (246.9 +/- 10.4 MPa), ultimate tensile strength (270.8 +/- 9.6 MPa), and uniform elongation (16.5 +/- 2.4%) exceeding industry standards.
