Liquid-like platinum-rich glasses
Abstract
Bulk platinum-rich glasses exhibiting high bulk moduli and Poisson ratios are introduced. A bulk modulus of 217 GPa and a Poisson's ratio of 0.43 are measured, the highest values reported to date for a metallic glass. The present glasses demonstrate an unusual capacity for "liquid-like" deformation characterized by low resistance to shear flow and high resistance to cavitation, enabling extensive bending ductility in the absence of fracture. An indirect estimate of the fracture toughness yields a value of ∼125 MPa m^(1/2).
