    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

    Freier Zugriff

    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 origination takes place subsurface from different material structural inhomogeneities. Fatigue origin has fine-granular area in the case of specimen tests under symmetrical cycle of cyclic loads but in the case of cyclic tension, origin has flat facet because of a-phase splitting. Experimental data dispersion under the constant stress level covered three orders.
