Stress-Strain curve for a ex-situ prepared Zr based metallic glass composite

  4. 4.  Tungsten fiber volume fraction:31 % (1.38 diameter) Sample length: 30 mm Mold cavity ( 6mm diameter, 55 mm length ). Glass-Alloy: Why Tungsten? : It increases Toughness (Tungsten has highest Tensile strength among pure metal) Compressive Fracture stress of BMG Composite (1783 Mpa) found to be slightly lesser than the Fracture stress of BMG (1904 Mpa). Fracture Strain of BMG Composite (0.06) is 10 times of BMG (0.558). Deformation occurs, as in glass by the propagation of localized shear bands (at an angle of 45 to the compressive axis). But the interaction of shear bands with the W wires results in the generation of multiple shear bands in the Tungsten and substantial plastic deformation. Greatly desired in the design of W- based armor piercing kinetic energy penetrators
