マグネシウム処理球状黒鉛鋳鉄の黒鉛核 Nucleus of Spheroidal Graphite in Magnesium Treated Cast Iron
The structure of spheroidal graphite in an magnesium treated spheroidal graphite cast iron was studied by a combined use of the high performance microscopic instruments : SEM with EDS, EPMA, AES and TEM. A spherical sulfide (Mg, Ca) S of about 1μm diameter is found near the center of graphite spheroids and is regarded as a nucleus for the graphite. A spherical MgO of about 0.2 μm diameter is found in the sulfide and is speculated to be a nucleus for the sulfide.
