Unformatted text preview: structures created. This generally has the effect of hardening the material while simultaneously making it more brittle. In many instances this may be a desirable trait but the intended use of the material should be known before such a technique should be employed as a loss of ductility will be incurred. This fast solidification will also affect the ratio of dendritic to lamellar structure. • Prepare an excel graph showing fractional amount of micro constituents primary alpha and eutectic solid (alpha + beta), as a function of alloy composition (in wt% Si) for hypoeutectic and eutectic sand cast Al-Si alloy....
