The present invention provides non-axially symmetrical manufactured parts
of thickness less than 10 mm, made of .beta. or quasi-.beta. 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 .mu.m to 300 .mu.m. The invention also provides a
method of manufacturing the parts by forging.
