Morphology of Chromium in Cu- 2.0%~4.2%Cr Alloys
The microstructures of Cu-Cr alloys with 2.0-4.2wt%Cr have been studied. Very little dendritic copper was found in supereutectic Cu-Cr alloy containing 2.4wt%Cr. When Cr content reached to 4.2wt%, square-like section Cr fibers other than round fibers were observed besides primary dendritic chromium in the Cu-Cr alloy. The fibrous Cr particles are eutectic chromium phase.
