    Abstract: A method of manufacturing a multilayer material including a back metal and a metal plate made from a metal differing from the back metal is disclosed. The method includes heating powder of the metal formed into the metal plate in a reducing atmosphere so that an oxide on a surface of the metal powder is deoxidized, and spreading the deoxidized metal powder onto the back metal and irradiating laser beam having an energy density of 10 to 100 kW/cm2 onto the metal powder spread on the back metal so that the metal powder is partially heated to be melted, while the laser beam is moved relative to the spread metal powder, and quenching the melted part of the metal powder at an underside of the back metal so that the melted part is rapidly solidified, whereupon the multilayer material has a dendritic structure in which the metal plate extends substantially vertically from a surface of the back metal, and the dendritic structure has a crystal grain size equal to or smaller than 0.02 mm at a cut surface thereof parallel to a surface of the back metal and/or a dendritic arm spacing equal to or smaller than 0.02 mm at a cut surface thereof vertical to the surface of the back metal.

    Abstract: A copper base alloy suitable for use as a material for a sliding member used under severe sliding conditions such as a floating bush bearing of a turbocharger used in automobiles is disclosed. The alloy consists of, by mass %, 15 to 25% Zn, 4.2 to 10% Bi, 2 to 7% Mn, 1 to 3% Si and balance of Cu and unavoidable impurities, the alloy having a structure of which matrix is composed of null-single phase, wherein a eutectic structure of the null-phase and an MnnullSi compound and Bi particle are distributed throughout the matrix.
