Abstract:
For the development of aluminum scandium alloys to produce a hydrogen storage valves, various aluminum alloy series with different Sc and Zr contents are tested. The alloys are mainly characterized by hardness measurements and tensile tests. The hardening curves are recorded for different temperatures and compositions, and the selected parameters are validated with the corresponding mechanical tests. The alloys 5083 + 0.2% Sc and AlSi16Mg1Sc0.4 are selected for the production of hydrogen valves by forging and additive manufacturing.
