Ti-Fe alloys are primarily recognized for their application in hydrogen storage, particularly in the formation of iron-titanium-hydride when exposed to gaseous hydrogen, especially at low temperatures. This process allows for efficient hydrogen absorption and subsequent release upon heating. Ti-Fe alloys have been noted as a cost-effective solution for automotive fuel storage, although magnesium-hydride offers higher efficiency but at a greater expense. The discussion highlights the significance of Ti-Fe alloys in energy storage technologies, emphasizing their potential in the automotive industry.
