| Abstract: | The service life of vanadium-titanium C/V iron ingot mould is 25% higher than that of grey iron mould. The mechanical and heat resistance properties of the iron studied are improved. The distribution of vermicular graphite of this iron appears to be in aggregate mode. The matrix is mainly ferrite except the grain boundaries, where exist pearlite and vanadium-titanium carbides. |
