CALCULATE_FROM_START_TEMPERATURE
This command is for the SCHEIL module.
The CALCULATE_FROM_START_TEMPERATE command enables or disables the calculation of equilibria directly from the start temperature chosen in the START_WIZARD. By default this is disabled (set to N
). Enable this (set to Y
) if you want to obtain properties of the liquid phase (and gas phase if selected) before the solidification starts. Ordinarily the start temperature is only used as a start point in the search of the liquidus temperature, as the Scheil calculation starts from the liquidus temperature.
With this setting enabled single equilibrium calculations are performed at specific intervals above the liquidus temperature, and after that the Scheil solidification calculation proceeds as usual. The equilibrium calculations are performed at 50 Kelvin (K) intervals in the fully liquid region and at 5 K intervals in a possible two-phase (liquid/gas) region.
