Abstract (en)
[origin: WO9956122A1] Method and apparatus for determining the mechanical properties of stainless steel cables or wires, which compare the amount of martensitic phase induced by strain and the original austenitic phase in the cable under test. The original magnetic phase is determined by taking out a baseline reading of the BS for a master cable, chosen, for each stainless steel cable to be tested, from among the cable or an equivalent cable, and the amount of martensitic phase is determined by taking out successive readings of the BS for the cable. Comparison of the amount of martensitic phase induced by strain to the original magnetic phase is effected by determining a martensite index, which is the ratio of two phase parameters, which refer to the cable under test and to the master cable, respectively.
