Cu-Sn-Zn系の3元合金柱物の色彩と溶質量との関係 Relation Between Color and Solute Content of Cu-Sn-Zn Alloy Castings
Cu-Sn-Zn alloys with different solute content were cast, and the spectroscopic surface reflectance of the alloys was analyzed. The principal component analysis was carried out with spectra at wavelength ranging from 450 nm to 650 nm to obtain a sub-space composed of 7 eigen vectors. The solute content of the alloy estimated with the sub-space was in good agreement with the nominal composition. At higher solute content, the estimated value varied considerably. The analysis with focussed light beam confirmed that the macrosegregation in the specimen caused variation of data at higher solute contents.
