Hydrogenation Effect

Hydrogenation effect on the development of superplastic deformation in the submicrocrystalline Ti–6Al–4V alloy at temperatures (0.4–0.5)Тmelt is investigated. Hydrogenation of the submicrocrystalline Ti–6Al–4V alloy to 0.26 mass% during superplastic deformation is found to result in solid solution strengthening, plastic deformation localization, and as a consequence, decrease of the deformation to failure. Possible reasons for the decrease of the flow stress and increase of the deformation to failure in the submicrocrystalline Ti–6Al–4V–0.26H alloy during deformation under conditions of superplasticity and simultaneous hydrogen degassing from the alloy are discussed.

Effect Of Oxygen

Oxygen plays very important roles in titanium and its alloys. Solute oxygen in titanium alloys leads to solid solution strengthening, suppressing the precipitation of the athermal omegaor orthorhombic martensite phase, enhancing the formation of the -case, etc. The proper using oxygen is effective to improve the mechanical functionalities of titanium alloys. However, the role of oxygen in titanium alloys is still not well understood. Therefore, the effect of oxygen on the mechanical functionalities such as strength-ductility balance, hardness, and Young’s modulus in Ti-29nb-13Ta-4.6Zr was investigated.

ABSTRACTThe temperature dependence of the flow stress in the B-doped DS Ni3Al containing Si as well as transition metal elements was systematically investigated by tensile tests. The effects of the alloy elements on the magnitude of the positive temperature dependence of the flow stress were evaluated. The calculated activation energy which results in the anomalous mechanical behavior the Ni3Al decreases for each element addition. The flow stress near liquid nitrogen temperature, taken as a measure of the degree of solid solution strengthening, increases linearly with the element concentration. The influences of the element additions on the solid solution strengthening were discussed. Also discussed were the mechanisms of the anomalous mechanical behavior in the Ni3 Al affected by the element additions.

Solution Strengthening

Solid solution strengthening of the unordered γ matrix phase by alloying elements is of great importance during creep of Ni-based superalloys, particularly at high temperatures above 1000 °C. To study the role of different potent solutes, we have conducted creep experiments on binary Ni-2X alloys (X = Mo, Re, Ta, W) at 1000 °C, 1050 °C, and 1100 °C at a constant stress of 20 MPa. Compared to mechanical tests below 800 °C, where the size of the elements mostly determines the solid solution hardening contribution, the strengthening contribution of the different alloying elements above 1000 °C directly correlates with their diffusivity. Therefore, elements such as Ta that lead to strong solid solution hardening at low temperatures become less effective at higher temperatures and are exceeded by slower diffusing elements, such as Re.
