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

EFFECTS OF Al-5TI-1B MASTER ALLOY AND HEAT TREATMENT ON THE MICROSTRUCTURE AND DRY SLIDING WEAR BEHAVIOR OF AN Al-12Zn-3Mg-2.5Cu ALLOY
In this study the effect of Al–5Ti–1B grain refiner on the structural characteristics and wear properties of Al–12Zn–3Mg–2.5Cu alloy was investigated. The optimum amount for Ti containing grain refiners was selected as 2 wt.%. T6 heat treatment, (i.e. heating at 460 °C for 1 h before water quenching to room temperature and then aging at 120 °C for 24 h) was applied for all specimens before wear...
متن کاملEffect of Al–5Ti–C Master Alloy on the Microstructure and Mechanical Properties of Hypereutectic Al–20%Si Alloy
Al-5Ti-C master alloy was prepared and used to modify hypereutectic Al-20%Si alloy. The microstructure evolution and mechanical properties of hypereutectic Al-20%Si alloy with Al-5Ti-C master alloy additions (0, 0.4, 0.6, 1.0, 1.6 and 2.0 wt%) were investigated. The results show that, Al-5Ti-C master alloy (0.6 wt%, 10 min) can significantly refine both eutectic and primary Si of hypereutectic ...
