Energy-efficient method for developing in-situ Al-Cu metal matrix composites using microwave sintering and friction stir processing

Abstract The problems associated with the fabrication of in situ metal matrix composites (MMC) by conventional methods can be avoided using microwave sintering and friction stirring combination. current study investigates mechanical electrical properties pure aluminum (Al-100 wt%) Al-Cu MMC. results showed that excellent ultimate tensile strength, toughness, conductivity acquired simultaneously. obtained strength case Al-100wt% (184.5 MPa) has improved two-fold than a typical commercially AA1016 (90 MPa). Similarly, developed (88.87% IACS) is 1.4 times higher compared to alloy (62% IACS). For MMC copper added steps 5 wt% (5%, 10%, 15%, 20%). maximum (205.2 (71.53% for Al-10wt%Cu are alloy. present investigation suggests novel processing route opens up new research avenues field solid-state materials processing.
