摘要： A testing method for determining the hardness of a micro region, into which an indenter is pushed, from an indentation curve indicating a relation between a penetration depth observed when an indenter in an arbitrary shape is pushed in and an indenting force, characterized by comprising

(1) measuring, in addition to macro hardnesses, relations between penetration depths observed when an indenter in an arbitrary shape is pushed in and indenting forces, for a plurality types of standard samples,
(2) determining a reference function indicating a macro hardness by standardizing a relation between an indenting force and a macro hardness with the same penetration depth used as an index, for indentation curves of a plurality types of standard samples indicating relations between penetration depths and indenting forces,
(3) measuring relations between penetration depths and indenting forces for arbitrary samples, and
(4) determining the hardness of a micro region from the measured values according to the reference function, by which the hardness of a micro region such as a nanometer region is evaluated accurately.

摘要： A method of manufacturing a fine multifilamentary Nb-Ti based superconducting wire was disclosed, which comprises a first step of processing an alloy consisting essentially of 10 to 50 atomic % of niobium, 40 to 75 atomic % of titanium and no higher than 30 atomic % of least one element selected from a group consisting of hafnium, tantalum and tungsten to form an alloy wire, a second step of covering said alloy wire with a stabilizer, cold drawing the resultant wire, bundling a plurality of a stabilizer-clad wires thus obtained, covering the bundle of wires with a stabilizer, and extruding and cold drawing the resultant bundled wire to thereby form a multifilamentary wire, and a third step of thermally treating the resultant multifilamentary wire at a temperature of 250 to 600°C and drawing the resultant treated multifilamentary wire to a reduction rate of 30 to 99.9 %. The third step is carried out more than once.
