Use of differential interference contrast microscopy to detect duplex carbides in alloy white cast irons.
Metall Trans, A, Phys Metall Mater Sci 1991 Jul; 22A:1673-1674
The purpose of this U.S. Bureau of Mines communication is to show that the relief that develops during metallographic polishing, from the differences in hardness of m7c3 carbides, m3c carbides, and an austenitic or martensitic matrix, can be used to detect duplex carbides by utilizing differential interference contrast microscopy.
