(1), gray cast iron mechanical properties and the organization of the matrix and graphite morphology. Gray cast iron in the sheet of graphite on the matrix of the serious separation in the sharp corners of the graphite easily lead to stress concentration, gray cast iron pieces of tensile strength, plasticity and toughness is much lower than steel, but the compressive strength and steel equivalent, is also commonly used Cast iron in the mechanical properties of the worst cast iron. At the same time, the matrix of the gray cast iron mechanical properties also have a certain impact, ferrite matrix gray cast iron graphite sheet, strength and hardness of the lowest, so the application of less; pearlite matrix gray cast iron graphite small, have a higher Strength and hardness, mainly used to manufacture more important castings; ferrite-pearlite matrix gray cast iron graphite graphite pearlite gray cast iron slightly thicker than the performance of pearlite gray cast iron. So the industry is more used pearlite matrix gray cast iron.
(2) The metallurgical factors of nodular cast iron with large section (wall thickness greater than 120mm) and the corresponding production process are studied. The use of appropriate amount of yttrium heavy rare earth compound nodulizer, forced cooling, the order of solidification, delayed breeding, if necessary, add a trace of antimony, bismuth, etc. to prevent the central part of ductile graphite distortion and loose tissue, has been successfully produced The 38 tons of large-scale complex structural parts, 17.5 tons of heavy diesel body, section 805mm ductile iron roll.
Ductile iron pipe and horizontal continuous casting ductile iron profiles. The physical properties such as specific gravity, thermal conductivity and electromagnetism of rare earth magnesium nodular cast iron were measured. The influence of graphite and matrix on the properties of nodular cast iron was studied by metallographic standard. The properties of ferrite nodular cast iron under normal temperature, low temperature, static state and dynamic condition were systematically determined. In addition, the stress-strain behavior, the small-energy multi-impulse resistance and the fracture toughness of the rare earth magnesium nodular cast iron have been studied and used to guide the production. Combined with the application of ductile iron gear, also systematically studied the bending fatigue strength and contact fatigue strength of nodular cast iron, as well as nodular cast iron gear pitting, spalling mechanism.
