Material Interaction

A Multi Phase Field model is proposed to describe the microstructure evolution induced by laser-material interaction in Selective Laser Melting (SLM). On the basis of the free enthalpy, the nucleation and growth processes occurring during the relevant phase transformations are explicitly taken into account. Within this contribution, the focus is laid on the SLM processing of the titanium alloy Ti-6Al-4V with special emphasis on the transition between β-titanium and melt. The results are discussed and compared to those of more conventional modelling approaches.

In this study, a novel formulation of phase field model for representing solidification of polycrystalline metals is proposed. A quaternion-based crystal orientation representation is introduced into the KWC-type phase field model. Using this approach, three-dimensional rotation of crystal orientation can be represented by a direct extension of the conventional KWC model. A numerical simulation by the presented model is conducted, and the characteristics and adequacy of the model are discussed.
