Precipitates in typical aluminum casting alloys were identified by X-ray diffraction and electron probe microanalysis referring to colored optical micrographs. Colored optical micrographs ensure more accurate estimation of precipitates by observing their shape and color. Fine precipitates of ternary constituents in the bulk sample can be identified through electron probe quantitative microanalysis by comparing the weight ratio of two main constituents. The precipitates contain about 1% of each alloying element in the form of solid solution. Accurate analysis is achieved regardless of the influence of matrix by comparing analytical values between the precipitates extracted from the matrix and those at least 5μm in size in the bulk sample.
