Abstract (en)
[origin: EP1340832A1] Non-axisymetric manufactured products, with a thickness less than 10 mm are made of beta or quasi beta titanium alloys and have a core microstructure made up of whole grains with a leanness ratio greater than 4 and an equivalent diameter of between 10 and 300 microns. These products are made by forging and from titanium alloys of the Ti17 (TA5CD4 or TiAl5Cr2MO4) type. An Independent claim is also included for the fabrication of these products by forging.
