Mass production of tridimensional articles made of intermetallic compounds

摘要

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