The procedure uses a metal strip made from iron with proportions of copper, silicon, boron, niobium, cobalt, nickel, vanadium, chrome, aluminum, zinc, carbon, germanium, phosphorous, gallium, antimony, indium and beryllium, cast in an amorphous state, passed through an annealing furnace (3) and subjected to crystallisation. The strip (R) is taken round at least two pulleys (4) in an S-formation and maintained at a temperature of 530 - 700 degrees C for a period of 5 - 120 seconds and under an axial tension of between 2 and 1000 MPa. The effort is measured by a unit (6) connected to a braking module (5). |
