The chromium-carbon system up to 20 pct carbon was reinvestigated using metallographic, X ray, and thermal analyses. The transformation temperatures pertinent to the three known carbides were examined, resulting in higher temperatures than heretofore given for some of these transformations. Many attempts...

Portnyagin et al., (2009) as well as Batanova et al., (2014) have interpreted high melting degrees as evidence of high mantle potential temperature (Tp > 1400oC), which could have been caused by proto-Hawaiian plume proximity. Our data contradict this interpretation because mantle potential...
3.15 Metastable Melting Point of a Pure Element When an element exists in two allotropic forms, consistency regarding the metastable melting point of the low-temperature form must be considered. If Δcp between the two allotropic forms is assumed to be zero, the metastable melting point of the ...
A multianvil apparatus has been used to determine the pressure-temperature melting curve of forsterite from 9.7 to 16.5 GPa. At 10.1 GPa a singular point occurs that marks the change from congruent melting at lower pressures to incongruent melting (forsterite = periclase + liquid) at higher pres...
The method achieves overall savings of computational resources by 80% compared to current alternatives. We apply the method to the high-entropy alloy TaVCrW and calculate its melting properties, including the melting temperature, entropy and enthalpy of fusion, and volume change at the melting ...

The continuous growth of Bulk Si by temperature gradient zone melting method Temperature gradient zone melting (TGZM) method was used to obtain bulk Si continuously for the efficient separation and purification of primary Si from the Si-Al alloy in this work. The effects of alloy thickness, temp...

In other words,amorphous polymersand semi-crystalline polymers can be processed above theirglass transition temperatureand melting temperature, respectively.Figure 4.4shows the schematic of the melting process. During the process, polymer pellets ...
