主　　题：Al-Si aluminum foam closed-cell tensile property 

摘      要：Al-Si closed-cell aluminum foams of different densities were prepared by molten body transitional foaming *** tensile behavior of Al-Si closed-cell aluminum foam was studied and the influence of relative densities on the tensile strength and elastic modulus was also *** results show that the fracture surfaces of Al-Si closed-cell aluminum foam display quasi-cleavage fracture consisting of brittle cleavages and ductile *** tensile strength and elastic modulus are strictly affected by the relative density of Al-Si closed-cell aluminum *** increasing relative density,the tensile strength increases and the strain at which the peak strength is measured also increases;in addition,the elastic modulus increases with increasing relative density.
