FATIGUE CRACKING MECHANISMS OF TITANIUM ALLOY VT3-1 IN VERY-HIGH-CYCLE-FATIGUE REGIME

FATIGUE CRACKING MECHANISMS OF TITANIUM ALLOY VT3-1 IN VERY-HIGH-CYCLE-FATIGUE REGIME

Investigations and tests of specimens of VT3-1 titanium alloy were done in Very-High-Cycle-Fatigue regime. Specimens were manufactured from compressor disks of D30-KU engine, and tests under frequency 20 kHz performed on the special test-bed in laboratory of Paris University «ITMA». Crack originatio...
