摘要：

The generalized enthalpy method is a single domain method to describe heat and mass transport without the necessity to take the phase distribution or phase boundaries into account [A. Mackenbrock, K.-H. Tacke, Metall. Mater. Trans. B 26B (1996) 871-881]. Here, the temperature T is an independent parameter. The important quantity is the enthalpy H, which is used to calculate the energy flow. Hence, it is possible to simulate macroscopic multi-phase systems with reduced computational effort. Calculations were carried out, describing solidification and microstructure formation during continuous casting of peritectic steel grades. The binary Ti-Al system with its numerous intermetallic phases is modeled to describe solidification and phase formation at heterogenous laser welded interfaces. (c) 2005 Elsevier B.V.
