Effect of build geometry on the β-grain structure and texture in additive manufacture of Ti6Al4V by selective electron beam melting
TL;DR: In this paper, the effect of geometry on the variability in the grain structure and texture, seen in Tisingle bond6Al single bond4V alloy components produced by Selective Electron Beam Melting (SEBM), has been investigated.
Journal ArticleDOI
Microstructure and Mechanical Properties of Wire and Arc Additive Manufactured Ti-6Al-4V
TL;DR: In this paper, the macrostructure, microstructure and mechanical properties of a Ti-6Al-4V alloy after WAAM deposition have been investigated, and the average yield and ultimate tensile strengths of the as-deposited material were found to be slightly lower than those for a forged Ti- 6Al 4V bar (MIL-T 9047), however, the ductility was similar and the mean fatigue life was significantly higher.

Evaluation of carbide grades and a new cutting geometry for machining titanium alloys
R. Komanduri,W.R. Reed +1 more
TL;DR: In this paper, a new cutting geometry consisting of a high clearance angle (from 10° to 15°) together with a high negative rake angle ( from −10° to −15°) is proposed for increasing cemented tungsten carbide tool life during the machining of titanium alloys.
