| Abstract: | 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. |
