A LITERATURE SURVEY OF THE EFFECTS OF CERTAIN MINOR ELEMENTS ON THE PROPERTIES OF NODULAR IRON.
Abstract
Minor elements often exert an effect on either the metal matrix or the graphite shape. Some elements, such as titanium, tend to cause flake graphite in nodular iron, resulting in low ductility. Other elements, such as tin, favor the formation of pearlite in the as-cast condition and increase time of annealing for ferritic nodular iron. The effects of many elements in nodular iron can be neutralized by cerium and other reactive elements. The effect of any one element is largely dependent on the presence of other minor elements and certain variables such as section size and heat treatment. A discussion is given for the following elements: carbon, silicon, magnesium, manganese, nickel, molybdenum, sulfur, phosphorus, chromium, vanadium, boron, copper, tin, arsenic, antimony, aluminum, lead, titanium, bismuth, tellurium, cerium, and a few other minor elements.
