Casting technology of gray cast iron engine cylinder block

The growth mechanism of tin crystal was discussed by means of lower microstructure observation and thermodynamic calculation. The effects of tin grown at different stages (crystallization and crystallization) on the microstructure, mechanical properties and machinability of gray cast iron were studied. The effects of different proportions of scrap +...
