摘要： A copper-based sliding member having excellent resistance to corrosion with sulfur and a Vickers hardness of 80 to 150, prepared by bonding to a backing metal layer a sliding layer comprising more than 35% by weight but not more than 43% by weight of Zn, the balance being composed of Cu, by a pressure-bonding method, subjecting the pressure-bonded assembly to diffusion-annealing and subjecting the assembly to work-hardening treatment to allow the sliding layer softened by the diffusion-annealing to have a Vickers hardness to 80 to 150. Said sliding member is excellent in resistance to corrosion with sulfur even under the conditions that a lubricating oil having a high sulfur concentration is used and also excellent in wear resistance.

摘要： A magnetic steel sheet containing, on a weight basis, 0.2 to 6.5% of Si and 0.03 to 2.5% of Mn, having a crystallographic texture wherein the density of aggregation of {100} planes parallel to the surface of the sheet is not less than 10 times that of non-oriented crystal grains, and having a demanganized layer in which the concentration of manganese decreases from the interior of the sheet toward the surface of the sheet, wherein the ratio between the concentration of manganese in the surface portion of the sheet and that in the mid depth portion of the sheet is not more than 0.90 and wherein the maximum ratio of reduction in the concentration of manganese within the demanganized layer is not more than 0.05 wt %/.mu.m. Magnetic characteristics of the magnetic steel sheet improved by adopting the average grain diameter 0.25 to 10 times the thickness of the sheet and by applying to the sheet a tension smaller than the elastic limit of the sheet in a direction parallel to the surface of the sheet. By employing an appropriate ratio of reduction in the Mn concentration, a relatively high magnetic flux density is obtained without a sharp increase in magnetic flux density, and core loss reduces, thereby providing a non-oriented or doubly oriented magnetic steel sheet having excellent magnetic characteristics and blanking performance.
