One of the most promising properties of glassy metals is their high strength combined with high malleability. In usual crystalline materials, one finds an inverse relation between the two properties, whereas for many practical applications simultaneous presence of both properties is desirable. One residual obstacle to practical applications that is likely to be overcome is the fact that glassy metals will crystallize at relatively low temperatures when heated slightly.
21. The author is primarily concerned with discussing
crystalline solids and their behavior at different temperatures
molten materials and the kinetics of the formation of their crystalline structure
glassy metals and their structural characteristics
metallic alloys and problems in determining their density
amorphous materials and their practical utilization
22. The author implies that the rate at which the molten materials discussed in the passage are cooled is a determinant of the
chemical composition of the resulting solids
strength of the chemical bonds that are formed
kinetics of the materials crystalline structure
structure the materials assume
stability of the materials crystalline structure
