Abstract Scope This work is supported by the Quality Made program from the Office of Naval Research. The room temperature microstructure of Ti-6Al-4V in multi-bead laser weld deposited builds is characterized by predominantly lamellar α phase growth with interlamellar β. This microstructure is the result of a complex position dependent thermal history from subsequent layer depositions. Several α morphologies and different lamellar sizes appear depending on local β character and cooling rates, which can affect the bulk mechanical properties of the material by causing local changes. This work attempts to model location referenced microstructural evolution in laser-wire deposited parts using a classical nucleation and growth model. Additive isothermal time steps in a JMAK type transformation with impingement correction are taken to approximate the cooling curves. Predicted values include area fractions of grain boundary, colony, basketweave, and martensitic α phase, as well as average lamella thickness. Results were compared to actual built structures.
