Provenience Status/Description Metallography Elemental/Hardness
Alloy: arsenical bronze
Where Cut: cross section of shaft
How Mounted: cross-section mounted cut side up
Structure: As-cast.
Metallographic description: 2% Sn, 4% As. The microstructure is cored dendritic, which appears at low magnification to be single phase. At 600x, however, there are small bits of what may be another phase, not alpha+delta eutectoid, but perhaps peritectic. Related to the As? There is little corrosion.
