Thermophysical properties and eutectic growth of electrostatically levitated and substantially undercooled liquid Zr91.2Si8.8 alloy

Liquid Supercoolability and Synthesis Kinetics of Quinary Refractory High-entropy Alloy

“…The thermophysical properties such as the density and specific heat of liquid high-entropy alloys, particularly those in supercooled state, are their essential parameters to accomplish the material design, investigate the solidification process kinetics and optimize the microstructure and properties16171819202122. In the specific case of refractory tungsten-involving HEAs, almost all the conventional container-based measurement techniques become inadequate.…”

“…The realization of a remarkable degree of liquid supercooling requires for the effective prevention of the heterogeneous nucleation caused by the chemical reactions and container walls. Although the containerless processing by various levitation techniques151721232425 is a possible way to overcome this technical barrier, the experimental attempt to supercool liquid refractory HEAs and measure their thermophysical properties still remains to be a sort of adventure.…”
