Sintering during Electron Beam - Powder Bed Fusion (EB-PBF) of Ti6Al4V Alloy
Defect and Diffusion Forum, 2022The partial sinter between the powder particles during the electron beam – powder bed fusion (EB-PBF) process is fundamental to guarantee adequate thermal and electrical conductivities and conduct the process safely. The sintering degree is tuned by using the process parameters that, at the present day, are mainly optimised with an experimental trial ...
