A1 - Rehmer, Birgit T1 - Hardness and tensile strength of multifilamentary metal-matrix composite superconductors for the Large Hadron Collider (LHC) JF - Journal of materials science N2 - Conventional indentation hardness measurements to obtain load independent Vickers hardness values for the different phases in multifilamentary superconducting (SC) wires are described. The concept of composite hardness is validated for a binary metal–matrix metal–filament Nb–Ti/Cu composite wire. The tensile materials properties of the individual wire components are estimated from their indentation hardness. The potential and limitations of this approach are critically discussed, based on a comparison with ensile test results obtained for wires and extracted Nb–Ti filaments.
