Abstract

The fabrication of near net shaping parts with functionally graded materialsusing laser rapid forming have been considered as a signification and promising technology. In this paper, the graded material of the Ti6Al4V/ Rene88DT superalloy was fabricated using laser rapid forming. A compositional gradient, from 100% Ti6Al4V to Ti6Al4V-38% Rene88DT superalloy, was achieved within a length of ∼54mm. The solidification behavior and the morphological evolution of Ti6Al4V/Rene88DT functionally graded material formed by a laser rapid forming process were investigated. Phase formation and microstructure evolution along the compositional gradient direction was analyzed by the thermodynamic and the microstructure selection models based on the maximum interface temperature criterion.
