Unformatted text preview: primary α constituent. Also as the silicon content increases, the fractional amount of the microconstituent eutectic solid increases. This eutectic solid consists of a mixture of the α and β phases. This is also noted on the graph by the increasing silicon curve. • Increased silicon content corresponds to lower ductility; however, the ability to flow is increased. • The microstructure gives evidence of the composition of the specimen. For a higher silicon composition, more β will be present and the specimen will be both harder and stronger; vise versa for lower compositions. The microstructure itself is in a way a physical layout of the specimen. Depending on the microstructure of the alloy, it will handle and react to forces in certain ways....
