Abstract In grey cast iron, sulfur is concentrated in the liquid, flake graphiteand on the edge of D-type supercooled graphite eutectic cells, but less sulfur is inaustenite. Besides, the content of sulfur in A-type graphite is higher than that inDtyp graphite, and the sulfur content in eutectic austenite is a little higher thanthat in primary austenite. While in nodular cast iron, less sulfur is in liquid andaustenite, but more in nodular graphite.

Key words: cast iron autoradiograph sulfur graphite
