The electron beam evaporation and deposition process

Abstract

The electron beam evaporation and deposition (EBED) process produces virtually defect-free ingots, disks and cylindrical shapes. When produced by EBED, high-temperature alloys have virtually no inclusions and titanium alloys have essentially no low-density inclusions (Type I defects). Most alloys produced by the process have grain sizes of less than 10 μm and are superplastic. Envisioned applications of EBED include the production of: complex, cylindrical shapes; high-purity sputtering targets; higher-fabricability alloys; and hot-section disks and compressor for aircraft engines.
