Effect of aluminum on hydrogen absorption kinetics of tantalum

•The hydrogen absorption kinetics in Ta–Al alloys is investigated for the first time.•The rate constant for hydrogen absorption increases with increasing temperature.•The three-dimensional diffusion is the rate-limiting step of hydrogen absorption in Ta–Al alloys.•The apparent activation energy for...
