. Fig. 23.27 a SEM BSE image and X-ray intensity maps for Al K-L2,3,
Cr K-L2,3, and Co K-L2,3. Note the shadowing effect of the particle thick-
ness causing attenuation of X-ray intensity. b X-ray intensity maps for

Mo L 3 -M4,5, and Ni K-L2,3, and a color overlay with Mo L 3 -M4,5 = red, Ti

K-L2,3 = green, and Ni K-L2,3 = blue. Note the localization of Ti and Mo in

inclusions, and the solidification dendrites outlined by Ti
