Abstract

The fabrication of near net shaping parts with functionally graded materials using laser rapid forming have been considered as a signification and promising technology. In this paper, a graded binary Titanium-Nickel alloy has been deposited using laser rapid forming from a blend of elemental Ti and Ni powders. A compositional gradient, from elemental Ti to Ti-23.2at%Ni, was achieved within a length of ≃25mm. The solidification behavior and the morphological evolution of Ti/Ni functionally graded material formed by a laser rapid forming process were investigated. a series of phase evolutions: α→α+β → α+β+Ti2Ni → β+Ti2Ni along the compositional gradient have occurred. Phase formation and microstructure evolution along the compositional gradient direction was analyzed.
