Measurements of liquid metallic systems show a clear indication of hysteretic behaviour of their volume vs. temperature. The highly precise measurements are done in an electrostatic levitator with optical control of the volume and laser heating. The

The coarsening of dendrites in two bulk metallic glass matrix composites was investigated using noncontact techniques in a high vacuum electrostatic levitator. Progressive degrees of coarsening were observed after isothermal holds of varying duration

Catastrophic amorphization of crystalline alloys supersaturated beyond a critical concentration has been postulated by Fecht, Desre and Johnson [Philos. Mag. B59 (1989) 577]. NbPd is a good candidate system for testing their ideas because of its p

The liquid density of Ti–6Al–4V was measured over a temperature range from 1661 to 1997 K that included undercooling by as much as 280 K. The sample was levitated in an electrostatic levitator and video imaging technique was used to capture the v
