This article presents typical values for the most used types of thermophysical property data that are needed for processing and modeling of solidification and casting processes. It describes methods to determine thermophysical properties, such as specific heat capacity and enthalpy of transformation; enthalpy of melting; solidus and liquidus temperatures; coefficient of thermal expansion; density; surface tension; viscosity; electrical and thermal conductivity; and emissivity.
There are several main sources of thermophysical property data that provide the most authoritative and comprehensive compilations of critically and systematically evaluated data that are presently available. This article provides thermophysical property data to assist in the materials properties selection for the simulation of casting processes. The measurements of thermophysical property are difficult due to high temperatures and the reactivity of some alloys. The article discusses strategies adopted to minimize the effects of high temperatures and the reactivity of alloys. It presents thermophysical properties for pure metals and some commercial alloys, and tabulates enthalpy of fusion and the solidus and liquidus temperatures for various alloys of commercial interest. The article also tabulates density, thermal conductivity, surface tension, and viscosity for some commercial alloys.
