Abstract
A conception of "frequency factor" is suggested for improving the accuracy to forecast the shrinkage defects. It shows that an sssociate use of the frequency factor and the criterion G/R could remarkably enhance the reliability and accuracy of forecasting. The numerical value of the criterion is related to the temperature range of solidification of the alloy.
