| 摘要 |
The invention relates to the processing of pseudo-ß-titanium alloys and can be used for manufacturing structural parts and assemblies in aerospace engineering. In the manufacture of deformed articles from pseudo-ß-titanium alloys, an ingot of a titanium alloy comprising aluminium, vanadium, molybdenum, chromium, iron, zirconium, oxygen and nitrogen is produced. The ingot is subjected to thermomechanical processing by means of repeated heating, deformation and cooling. High-precision stamped articles with a thickness in cross section of 100 mm or greater and a length of greater than 6 m are produced with stable, high values for ultimate tensile strength and fracture toughness. |
