“…Rapidly solidified ribbons were prepared by the single roller melt-spinning technique. During rapidly solidification, a stream of molten alloy with a temperature 950 • C was ejected by pressured argon from 0.5 mm diameter orifice onto the brass wheel that rotating at 13,15,20,25,27,30,32, and 35 m/s circumferential velocity. Resulted ribbons were typically several meters long, 1-5 mm wide and 53-158 m thick.…”

“…Sb in the form of Al-Sb master alloys is extensively used as an alternative to Na or Sr in the production of Al-Si alloys by the permanent mold process. In the industrial practice, Sb is often added to the Al-Si melts in the form of Al-Sb master alloy [19,20]. It has been also reported that Sb results in fine lamellar morphology of eutectic silicon [21].…”

“…More recently, Sb is extensively used as an alternative to Na and Sr in the production of Al-Si alloys by the permanent mold process [1][2][3][4][5][6][7][8]. It has been found that Sb can effectively refine the Al-Si eutectic structure at relatively high cooling rates, providing a low susceptibility to gassing and excellent casting properties [9].…”

In the present work, the microstructural characterization of a melt-spun Al-20 Sb alloy has been carried out using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The phases present in the melt-spun Al-20 Sb alloy were determined to be ␣-Al and AlSb, identical to those in the ingot-cast alloy. The microstructure of the melt-spun Al-20 Sb alloy is dominantly composed of primary AlSb dendrites embedded in the ␣-Al matrix, different from that of the ingot-cast alloy composed of primary AlSb plates within an ␣-Al/AlSb eutectic matrix. In addition, some areas comprise primary AlSb particles within the ␣-Al matrix in the melt-spun alloy.
