چکیده انگلیسی
In the present study, a Zr-based amorphous alloy matrix composite reinforced with tungsten porous foam (internal porosity; 30 vol.%) was fabricated without pores or defects by liquid pressing process. The compressive test results indicated that the composite was not fractured at one time after reaching the maximum compressive strength, but showed considerable plastic strain as the compressive load was sustained by the foam. The strength (2764 MPa) and ductility (39.4%) were greatly improved by homogeneously dispersing the stress applied to the matrix because the tungsten foam and matrix were simultaneously deformed without showing anisotropic deformation due to excellently bonded tungsten/matrix interfaces.
