Mechanical behavior of open-cell aluminium foams filled with tin-bronze foams

The interior pore of open-cell aluminium foams filled with bronze is a new method preparing composite. voids were fabricated by in situ thermal decomposition space-holder powder metallurgical sintering process. Cu3Sn phase content observed to increase through transformation at the expense Cu6Sn5 and aluminium-matrix during isothermal aging. effect porosity on interface microstructure between filler has been investigated. 'bulge' shape appears compressive stress-strain curve composite, which sharply different from single-component metal foams. According characteristic stress distribution, curves can be divided into 4 stages: quasi-linear region, decrease plateau region densification region. relative density first maximum absorbed energy composite was also studied. results suggest incorporating pores an effective improve mechanical properties
