| Shrnutí: | Title screen The effect of hydrogen charging, ultrasonic treatment, and hydrogen charging after ultrasonic treatment on the fatigue life of VT6 alloy is investigated. Ultrasonic treatment causes the formation of a continuous nonetching ?2(Ti3Al) layer within the surface layer, which reduces the fatigue life. Below this layer there are bands of the ?2(Ti3Al) phase which, on the contrary, increase the fatigue life. These two effects together give a 1.3-fold increase in the fatigue life of the alloy. A catastrophic decrease in hydrogen charging after ultrasonic treatment is explained by the formation of regions of short-range displacements with a bcc lattice similar to the ? phase. As a result of radial shear rolling, a martensitic phase with very high strength is formed in the alloy. Its formation is predicted by positron annihilation spectroscopy and is detected by transmission electron microscopy. The high stability of the martensitic phase contributes to the lower fracture toughness of the alloy processed by radial shear rolling. Режим доступа: по договору с организацией-держателем ресурса |
