Properties of Titanium Alloy Electron Beam Additive and Forging Composite Manufacturing
In order to solve the problem of high manufacturing cost of large and complex titanium alloy structural parts fabricated,"additive manufacturing+forging"combing the advantages of rapid prototyping in additive manufacturing and high precision in equal-material manufacturing was studied.Through metallographic analysis,spectral analysis and other test technologies,organization and chemical composition of the cladding were characterized.The results show that the widmanstatten structure of cladding metal is found and the ratio of length to width decreases with the increase of cladding height,it has a high Al element at interface content and strengths of the joint with forging are significantly higher than standard for forgings.
