Non-Contact Measurement of Thermophysical Properties of Fe, Fe–C, and Fe–C–Mn Alloys in Solid, Supercooled, and Stable Liquid Phases

Density, excess volume, and structure of Fe–Cr–Ni melts

“…The ρ L of Fe and Ni is determined to be 6.968 g cm −3 and 7.929 g cm −3 , respectively. Compared to the previous results, these values are in good agreement to within ±0.31% and ±0.68% for Fe 17,22,31 and Ni, 12,32,33 respectively, and reasonable deviations within ±1.07% and ±1.75% are also found for Cr (wt. %) Fe 12 and Ni, 34 respectively.…”

Formation of Metastable Crystals from Supercooled, Supersaturated, and Supercompressed Liquids: Role of Crystal-Liquid Interfacial Free Energy

“…All Ti-Zr-Ni liquids showed an ISRO which was measured by scattering experiments [7,29]. Simple crystalline phases of elemental transition metals and alloy liquids with bcc structure [21,[24][25][26][27] showed the highest undercooling (∆T r = (T − T r )/T l = 0.18, where T r and T l is recalescence and liquidus temperatures, respectively) and interfacial energy (σ(J/m 2 )) per fusion enthalpy (∆H f ) (i.e., Turnbull coefficient α (= σ/∆H f = 0.39~0.61)), compared with other crystal phases. For icosahedral quasicrystalline phases (i-phase), the lowest undercooling and α were obtained with 0.1 and 0.32~0.34, respectively [7,8,21].…”

“…Using the combined techniques, the interfacial free energy and SROs of supercooled liquids have been reported with elemental metals (Ti [22][23][24], Fe [25][26][27], Ni [23,27,28], Zr [28,29]) and many alloys [7,8,21,[29][30][31][32][33]. Particularly, a combination of electrostatic levitation (ESL) and X-ray synchrotron scattering revealed for the first time the relationship between SRO and nucleation barriers with Ti-Zr-Ni alloy liquids [17].…”
