Based on analyzing mechanisms of nodular graphite foming in the past ,this paper discuss spheroidal graphite growth mechanisms by thermodynamics factors witch is interface energy between graphite and liquid iron , and kinetics conditions which is spheroidizing and surface active element(Ce,Mg,S,P) , C,Si element distribution , and C,Fe element diffusion in the melt .

One kind of nodular iron with molybdenum and moderate silicon was developed according to foreign relevant technical standards.

Optimum microstructure with excellent strength and toughness were designed in a nodular iron in the light of the understanding on the mechanical behaviour of graphite and graphite-matrix interface in cast iron.

In order to find a quick and accurate test method for discriminating the nodular iron from the gray iron on the production spot, ultrasonic attenuation tests were conducted on both the nodular iron and gray iron specimens with different thicknesses by adopting the ultrasonic waves with different frequencies.
