The deuterium permeation behavior in W foil and W rod were studied by Gas Driven Permeation (GDP) method, in which the gas loading surface were parallel and perpendicular to the grain elongated direction respectively. The results show that the deuterium permeability and effective diffusivity in W foil were lower than that of W rod.
