Title: MILLING TIME — DEPENDENT MICROSTRUCTURE AND MECHANICAL PROPERTIES OF NANOSTRUCTURED <font>Al</font>–<font>Si</font> ALLOY
Abstract: Al –7% Si alloys were prepared by ball milling technique under different milling time. The effect of milling time on the microstructure and mechanical properties were studied. The results indicate that the grain size decrease with increasing the milling time, the average dislocation density, ρ, was found to exhibit a drastic increase by increasing the milling time, the median diameter, μ decreases, while the value of width parameter, σ is approximately constant with increasing the milling time. The value of Vickers hardness (HV) increases by increasing milling time, this increase was attributed to the refinement of grains with increasing milling time.
