Graphite flotation - GIESSEREILEXIKON.COM

Graphite flotation. Graphite diffusing from cast iron melts rising to the top of the melt. In metallographic specimen floating graphite is very clearly identifiable even with low degree of magnification. At broken or machined surfaces, the diffused and floated spherolites can be identified as dark spots even with the unaided eye ( Figures 1 to 3 ).
