| Abstract: | The relationships of specimen diameter, modulus of casting ( M c) and secondary dendrite arm spacing(SDAS) of casting were studied. The relative equation of SDAS and modulus of casting under the condition of sand casting was obtained through testing the SDAS of different section of A357 alloy castings under various solidification conditions. The effect of solidification condition on casting densification was also investigated and the reasonable solidification condition for high densification castings was determined. |
