Calculation of solidification-related thermophysical properties for steels

摘要: Special algorithms have been developed to calculate important solidification-related thermophysical properties: enthalpy and enthalpy-related data (i.e., specific latent heat), density, thermal conductivity for low-alloyed stainless steels. The are heavily based on the use of earlier phase transformation models, an interdendritic solidification model (IDS), austenite decomposition (ADC), which solve, as a function temperature, fractions compositions needed in these calculations. As result, properties can be calculated at any from 1600 °C 25 °C, taking into account discontinuities caused by special transformations ferritic, austenitic peritectic solidification, ferrite/austenite transformation, various structures) influenced steel grade cooling conditions.
