Selective electron beam melting of Ti–48Al–2Nb–2Cr: Microstructure and aluminium loss

In the present paper a broad parameter window for processing Ti–48Al–2Cr–2Nb by selective electron beam melting is investigated. Data for the aluminium loss during the process in relation to used beam parameters and process strategies for its minimisation are presented. Al losses as low as 0.5 at% w...
