The tensile strength and structure (dendrite arm spacing or D.A.S) of cylindrical castings were determined for specimens with different thicknesses and masses subjected to the T6 solution treatment, because they are expected to be affected by the casting modulus (volume/surface area) and the cooling rate (solidification time). When <i>V/S</i> of the castings increases, the cooling rate and the strength decreased, but D.A.S increases. The strength and D.A.S can be presented as a function of the nth power of the casting modulus <i>(V/S)</i>.
