ABSTRACT:
A process for mass production of three-dimensional articles made of intermetallic compounds based on titanium and aluminium by an electron beam melting technology. The articles are produced in successive sections from powders of the intermetallic compound with which the articles are to be produced. For each section, melting of the powders preceded by a preheating step is performed.
