The paper by Jan Schroers and William L. Johnson reports on the experimental evidence of significant global plasticity in a monolithic Pt$_{57.5}$Cu$_{14.7}$Ni$_{5.3}$P$_{22.5}$ bulk metallic glass (BMG). This material exhibits a plastic strain of 20% under compression and a strain exceeding 3% before failure during bending, which is unprecedented in metallic glasses. The high plasticity is attributed to a high Poisson ratio of 0.42, which allows shear bands to extend rather than initiate cracks, leading to multiple shear band formation. This results in a very high fracture toughness of approximately 80 MPa m$^{-1/2}$. The material also shows a high elastic limit and a low glass transition temperature, making it a promising candidate for structural applications. The study highlights the potential of BMGs with low glass transition temperatures to exhibit room-temperature ductility, as observed in this specific alloy.The paper by Jan Schroers and William L.
