Color Metallography

Abstract

The use of color in metallography has a long history, with color micrographs published over the past eighty-some years. A number of general articles have been published reviewing methods and applications. Natural color is of use in only a few classic metallographic applications. Prior to the development of wavelength-dispersive spectrometers and energy-dispersive spectrometers used on electron microprobe analyzers and scanning electron microscopes, the color of inclusions using different illumination modes was part of the identification schemes used. However, natural color has limited applicability. One 6061 image and text reference.
