Graded Microstructure of Additive Manufactured Ti-6Al-4V via Electron Beam Melting
Source abstract
Abstract
Electron beam melting (EBM) process is an additive manufacturing (AM) technique, which utilizes an electron beam to melt conductive metal powders under a high vacuum [1]. Typically, a raster/linear scan strategy is utilized in which the beam horizontally moves from left to right direction on the powder bed. Recently, a dehoff fill strategy which melts each 11 th point in a line , skips 5 lines, and repeats until each point is melted, was utilized to site-specifically control the crystallographic grain orientation in nickel base superalloy Inconel 718 systems However, whether the aforementioned phenomenon is universal in other alloy systems is still open to question. Here, we selected Ti-6Al-4V (one of the most vital engineering materials and has been applied in aerosapce and biomedical industry due to its high strengthto-weight ratio and ourstanding biocampatility) as the model system
