Abstract—Bulk metallic glasses (BMGs) of Pd–Cu–Si and Pd–Ni–P systems were formed from a melt in the
1970s–1980s. However, in view of the extremely high cost of the main component (palladium), they have been
outside the realm of special interest of scientists and engineers for a long time. Relatively recently, BMGs in
the form of macroscopic-sized ingots have been fabricated in alloys based on industrial metals (iron, copper,
magnesium, and titanium), which opened up wide possibilities for their application. BMGs possess high
strength, hardness, wear resistance, elastic deformation, and corrosion resistance. In this study, a review of pub-
lications is presented and main scientific achievements in this field are described. It is noted that main scientific
problems, which are not solved completely, are describing the BMG structure as well as vitrification and plastic
deformation, while the technical problem attracting the attention of scientists in many countries is to increase
the plasticity and impact fracture toughness of these materials.

Keywords: bulk metallic glasses, structure, vitrification, strength, ductility
