abstract = "The effect chemical composition on the shock response of two bulk metallic glass (BMG) alloys with slightly different elemental compositions (Zr55Cu10Ni5Al30 and Zr46Cu38Ag8Al8) has been investigated. Plate-impact experiments were conducted at a peak compressive stress of ∼10GPa, above the expected elastic limit of these alloys (∼7GPa). Velocity interferometry was used to measure the particle (up) and free surface velocity (FSV) histories. These measurements allowed calculation of the Hugoniot elastic limits and onset stresses of fracture (i.e. spall strength) for each alloy. The soft recovered specimens were characterized by means of optical and electron microscopy. It was found that the Zr55Cu10Ni5Al30 exhibited a higher HEL and spall strength and a smooth fracture surface morphology consisting of dimple-like features. Conversely, the lower spall strength of the Zr46Cu38Ag8Al38 alloy seems to correlate with rougher fracture surface that shows cup-cone features associated with a predominantly brittle dynamic fracture.",
