Enhancement of Activation and Hydrogen Storage Kinetics of TiFe(Mn) Using High-Pressure Sliding (HPS) Process

抄録

A titanium–iron intermetallic with minor addition of manganese (TiFe_0.7Mn_0.3) was processed by severe plastic deformation through high-pressure sliding (HPS). A rectangular strip sample was embedded in stainless steel and strained under a pressure of 4 GPa at room temperature. The hydrogen storage kinetics and activation of the HPS-processed sample were significantly enhanced in comparison with the as-received ingot without the HPS processing.
