Abstract
The present invention provides non-axially symmetrical manufactured parts of thickness less than 10 mm, made of β or quasi-β titanium alloy, having a core microstructure constituted by whole grains presenting a slenderness ratio greater than 4 and an equivalent diameter lying in the range 10 μm to 300 μm. The invention also provides a method of manufacturing the parts by forging.
