主　　题：cast Al alloy fracture toughness statistical model 

摘      要：The statistical model for the fracture toughness of a modified Al-7Si-0.45Mg cast alloy has been proposed on the basis of analysis of the correlation between the size distribution of crack nuclei and Si particles and of the micromechanism of *** suitable criterion of frac- ture toughness according to the model has been *** model has found a good explana- tion for the fracture feature,fracture toughness and microstructure,and agreed with the ex- periments very well.
