Impact of severe plastic deformation on microstructure and hydrogen storage of titanium-iron-manganese intermetallics

TiFe1-xMnx intermetallics (x=0, 0.15 and 0.3) were severely deformed by high-pressure torsion (HPT) to enhance their activation and air resistivity for hydrogenation. While the as-cast ingots hardly absorbed hydrogen (TiFe0.7Mn0.3 exhibited slow activation after an incubation period), the HPT-proces...
