Effect of compound treatment of rotating magnetic field and Al-5Ti-1B refiner on microstructure and properties of Al-5Cu alloy

The Al-5Cu alloys were prepared by different treatment methods, including adding a refiner Al-5Ti-1B, exerting rotating magnetic field (RMF), and compound of both RMF. effects methods on the microstructure, properties, solid solubility alloy investigated. optimal parameters addition amount confirmed experiment. Results show that either RMF or Al-5Ti-1B alone can refine grain size, refining effect be further improved with optimized (120 A current 8 Hz frequency) 1.0wt.% (RMF*+Al-5Ti-1B*). average size is decreased to 68.1 µm, which 60.8%, 21.1%, 83.5% lower than treated field, refiner, without any treatment, respectively. tensile strength elongation reach 232.5 MPa 18.6%, respectively, are obviously higher those Additionally, also compared other methods.
