Nanoembedded lead-tin alloys in aluminium matrix were synthsized by rapid solidification processing. These melt-spun aluminium alloys were then investigated using XRD, EDX and TEM. The XRD study reveals that the melt-spun samples contain elemental aluminium, lead and tin. The TEM analysis shows that embedded particles in aluminium matrix have a ditinct two-phase contrast of lead and tin. The lead and tin in these nanoalloys exhibits an orientation relationship with the matrix aluminium and with each other. DSC studies were conducted to reveal the melting and solidification characteristics of these embedded alloys. DSC thrmograms exhibit features of multiple solidification exothrms on thermal cycling, which can be attributed to sequential meltin and solidification of lead and tin in the respective alloys.
