Electron-beam melting of Ti–6Al–4V

Abstract

A program to recycle Ti–6Al–4V machine chip scrap by electron-beam (EB) melting is described. The advantages of utilizing EB melting are described in terms of the selection of raw materials, the unique characteristics of the EB hearth furnace, the alloying and refining reactions that are promoted, and the unique character of the solidification process. Experimental results are presented on a manufacturing technology program sponsored by the Air Force Materials Laboratory in which machined chips, sponge, and alloy elements are recycled into specification grade Ti–6Al–4V bar stock.

Electron Beam Sintering of Zirconium Diboride

“…Most electron beam fabrication research has been focused on high‐performance metallic materials such as aluminum, 5 tool steel, 6 and titanium alloys 7,10 ; little work exists on creating ceramic parts using this approach. In this research work, we have attempted the sintering of ZrB 2 powder materials using an electron beam.…”
