TY - GEN A1 - Scheuerlein, C. A1 - Rehmer, Birgit T1 - Tensile properties of a non-reacted internal tin NB3SN composite wire calculated from the vickers hardness of its individual phases according to the rule of mixtures T2 - Technical Note N2 - The load-independent Vickers hardness (HV) of the individual phases in a non-reacted Nb3Sn wire has been measured and the yield strength (YS) of the individual components estimated from the HV values. The YS and tensile strength (Rm) of the composite wire are calculated according the rule of mixtures (ROM). Calculated tensile properties are compared with tensile test results that were obtained for the entire composite wire, for the wire after removal of the Cu stabiliser and for single Nb-7.5wt.%Ta fibres.
