You start with the iron (of course) and then add more carbon than the iron would normally be able to absorb into the structure. Explaining the iron-carbon relationship in another way, it is like adding so much salt to your water that you reach a point no more salt will dissolve. By the way, this is what makes ductile iron different than steel. Steel only has as much carbon as the iron can absorb.Silicon, Sulphur, manganese, and oxygen all do their part in the mix to help the carbon to form into spherical graphite structures as the iron cools. This, admittedly, is an oversimplification of the process (after all, we are not training you for a metallurgical degree, th......url:http://www.zzebcorp.com |
