Effects of Water Cooling on the Microstructure of Electron Beam Additive-Manufactured Ti-6Al-4V

Effects of Water Cooling on the Microstructure of Electron Beam Additive-Manufactured Ti-6Al-4V

The inferior mechanical properties of EBAM Ti-6Al-4V samples are due to the coarse columnar grains containing coarse lamellar structures. One can expect that water cooling of the build platform will increase the cooling rate of the molten pool during the build-up process, causing microstructure refi...
