Abstract The crystallization kinetics of Zr{sub 58.5}Nb{sub 2.8}Cu{sub 15.6}Ni{sub 12.8}Al{sub 10.3} were studied in an electrostatic levitation (ESL) apparatus. The measured critical cooling rate is 1.75 K/s. Zr{sub 58.5}Nb{sub 2.8}Cu{sub 15.6}Ni{sub 12.8}Al{sub 10.3} is the first bulk-metallic-glass-forming liquid that does not contain beryllium to be vitrified by purely radiative cooling in the ESL. Furthermore, the sluggish crystallization kinetics enable the determination of the time-temperature-transformation (TTT) diagram between the liquidus and the glass transition temperatures. The shortest time to reach crystallization in an isothermal experiment; i.e., the nose of the TTT diagram is 32 s. The nose of the TTT diagram is at 900 K and positioned about 200 K below the liquidus temperature.
