SIZE DISTRIBUTION AND BEHAVIOUR OF VC PARTICLES IN FERRITIC NODULAR CAST IRON
1992
Size distribution and precipitation of VC particles in the ferritic nodular cast iron have been examined by techniques of ultrasonic screening, small angle X-ray scattering and chemical dissolution.The VC particles are sized over a wide range. The superfine ones, dispersed in the ferrite matrix, are the large majority. A saturated dispersion with ultrafine VC particles may be approached as the increasing of V content in the iron. This seems to play an important role in the precipitation strengthening for ferritic noldular cast iron.
