Ti-6Al-4V powder compacts were prepared using hot isostatic pressing (HIP), and the effect of powder size on microstructure and fatigue properties of HIPed powder compacts was investigated. The results show that the microstructure of powder compacts is fine and homogeneous. The volume fraction of equiaxed α phase in the powder compact decreases with the increase of powder size. The powder compact...
Room temperature tensile ductility of extruded Ti-47Al-1.5Nb-1Cr-1Mn-0.5B (at.%) with different surface topographies was investigated. Tensile specimens were subjected to grinding with sandpaper of different grits and electrolytic polishing to achieve different surface topographies. Surface morphology/topography and tensile ductility of different surface preparations were compared. Results show that...
Titanium offers performance as well as mass saving benefits in automotive components subjected to reciprocating and suspension loads and in components subjected to extreme temperatures and gradients. However, the extensive use of titanium is hampered by the high cost of the raw material and the special handling that is needed. This article outlines the technological and economic challenges faced and...
