【Abstract】 Analyzes and discusses the influence of residuals Mg、Re and S in cast iron on the microstructure and mechanical properties of ductile iron through crisscross experimentation on the basis of former experimental work, and suggests the optimal combination for the three factors mentioned above, from which the structures and properties needed in such an experimental condition can be obtained.更多还原
