Modeling of phase transformations of Ti6Al4V during laser metal deposition

[EN] The low density, excellent high temperature mechanical properties and good corrosion resistance of titanium and its alloys have led to a diversified range of successful applications. As a consequence, there is a demand of increasing the capabilities of processing such alloys. The laser cladding technique allows direct metal deposition with an excellent metallurgical bond and a pore free fine grained microstructure. A nonlinear transient thermo-metallurgical model was developed to study the technique with titanium alloys to get a better understanding of the thermal and metallurgical underlying aspects. The calculated temperatures and phase transformations are compared with experimental tests. © 2011 Published by Elsevier Ltd.This work is has been done under the research project MAT2008-06882-C04 funded by the Spanish government (MICIIN).Suárez, A.; Tobar, MJ.; Yañez, A.; Pérez, I.; Sampedro, J.; Amigó Borrás, V.; Candel Bou, JJ.
