Abstract

Semi-solid A356 alloy melt was prepared and formed by squeezing casting in Archimedes spiral experiment die

and then filling ability of A356 aluminum alloy was analyzed by measuring the length of the sample spiral line.By controlling the process parameters to obtain different solid fraction and shape factor

influences of the solid fraction and shape factor on the rheological filling ability of A356 alloy melt was investigated.The results reveal that

under the same process parameters

influences of the solid fraction on the rheological filling capacity of semi-solid alloy melt is the greater than that of the shape factor.And the rheological filling ability is decreased significantly with increasing in the solid fraction

and increased with the decrease of shape factor.
