摘要
We present a porous ductile Mo particles reinforced Mg-based metallic glass composite, exhibiting superior mechanical performance with up to 10% compressive strain and 1100 MPa stress at room temperature. For a given amount of particles, the porous particles will generate more interfaces between the reinforcements and matrix and, thus, can confine lots of microsized compartments of the Mg based glassy phase within the porous particles. This promotes the deformation to distribute more uniformly across the specimens, improving the ductility. We suggest that porous ductile particles might preferably be used to toughen amorphous materials with stubborn brittleness. (c) 2008 American Institute of Physics.
