Young's modulus for a dispersion strengthened Al-Fe-V-Si (FVS 1212) alloy has been measured using PUCOT (Piezoelectric Ultrasonic Composite Oscillator Technique), after melt spinning the alloy under different combinations of nozzle size, wheel speed and power input. It is found that the interactions among the three variables exert a strong influence of the Young's modulus. Young's modulus measurements using PUCOT were also made on melt spun ribbons of three other aluminum alloys. Electron diffraction patterns of the ribbon specimens suggest that crystalline structures lead to promote higher modulus in all the aluminum alloys examined.
