HYDROGEN PERMEABILITY THROUGH TANTALUM ALLOYS ALLOWED WITH Nb AND W
An analysis of studies of membrane alloys Ta77Nb23 and Ta94,9W5,1 was carried out with an estimation of their characteristics – thermal stability, strength – by measuring microhardness, matrix structure – by X-ray analysis, as well as the dynamics of hydrogen – diffusion (theoretically) and permeabi...

| description | An analysis of studies of membrane alloys Ta77Nb23 and Ta94,9W5,1 was carried out with an estimation of their characteristics – thermal stability, strength – by measuring microhardness, matrix structure – by X-ray analysis, as well as the dynamics of hydrogen – diffusion (theoretically) and permeability (experimentally). The efficiency of the hydrogen separation/purification using the Ta77Nb23 and Ta94,9W5,1 alloys was higher than that of palladium, measured under the same test conditions. |
