چکیده انگلیسی
Nanostructured Al–4Y–4Ni–X composites created by extruding atomized amorphous powders at different extrusion ratios were tested under high cycle bending fatigue at load ratios, R=0.1, 0.33 and −1 at room temperature, 149 °C and 260 °C. Increasing the extrusion ratio generally improved the fatigue life and the fatigue limits were well in excess of that obtained on conventional aluminum alloys at all temperatures tested. The fatigue limits obtained in this work were also compared to previously reported values for a nanostructured composite Al–Gd–Ni–Fe alloy produced via similar means.
