摘要： A non-destructive method for using the mechanical Barkhausen noise phenomenon, caused in fereromagnetic materials by the dislocation motion and the changing external mechanical loading, especially in determining the fatigue strength of the material. The test piece is cyclically loaded with continuously or incrementally increasing amplitude in the presence or absence of a stable magnetic field by which the test piece is magnetized and, simultaneously, measurement is made of the maximum value obtained as a function of one of: the effective value, the size distribution and the mean value of the mechanical Barkhausen noise pulses induced during fatigue of the test piece. The loading amplitude at which such maximum value is reached corresponds to a fatigue strength equal to the fatigue limit of the test piece, the latter having been subjected to a prior loading process to create a lattice defect pattern in the test piece when no stable magnetizing field is present. The prior loading process comprises the steps of cyclically loading the test piece externally with continuously or incrementally increasing amplitude and simultaneously measuring the changes in the effective value, size distribution or mean value of the mechanical Barkhausen noise pulses induced during fatigue of the ferromagnetic test material caused by such loading and decreasing the external loading to zero.

摘要： A method for producing fibrous monocrystals, i.e. whiskers, of high-temperature superconductive ceramics in their best superconductive crystal directions, thereby in the main avoiding the production of non-superconductive fibres and also the effect which decreases the superconductivity due to relatively weak superconductive crystal directions. Whiskers are produced by means of physical gas-phase coatings (physical vapour deposition = PVD), for example using radiofrequency magnetron sputtering (RF magnetron sputtering) or by means of chemical gas-phase coatings (chemical vapour deposition = CVD). The growth underlayer, i.e. the substrate, employed is a ceramic monocrystal surface in accordance with the (100) orientation, a ceramically coated metal surface or a smoothed or polished metal surface. It is typical of the latter alternative that the coating which is formed on the metal surface initially grows in a relatively weak superconductive crystal direction but then alters its growth to the best superconductive crystal direction and is at the same time transformed into whiskers.

摘要： A non-destructive method of measuring the fatigue limit of a ferromagnetic test piece by use of the mechanical Barkhausen noise phenomenon. The test piece is cyclically loaded with continuously or incrementally increasing amplitude in the presence of absence of a stable magnetic field by which the test piece is magnetized and, simultaneously, measurement is made of the maximum value obtained as a function of one of the effective value, the size distribution and the mean value of the mechanical Barkhausen noise pulses induced during fatigue of the test piece. The loading amplitude at which such maximum value is reached corresponds to a fatigue strength equal to the fatigue limit of the test piece, the latter having been subjected to a prior loading process to create a lattice defect pattern in the test piece when no stable magnetizing field is present. The prior loading process comprises the steps of cyclically loading the test piece externally with continuously or incrementally increasing amplitude and simultaneously measuring the changes in the effective value, size distribution or mean value of the mechanical Barkhausen noise pulses induced during fatigue of the ferromagnetic test material caused by such loading and decreasing the external loading to zero. This method offers the notable advantage that the endurance or fatigue limit can, in practice, be determined very quickly for example, in a period of only 15 minutes. Therefore, the method can in practice be applied to determine immediately whether or not the dynamic loading of a machine part is too large.
