    Abstract: The blade structure of a wind turbine which has enough strength for sporadic large load and increased durability. The blade can be formed into a thinner blade profile, with which blade performance is improved, increased efficiency of the wind turbine is attainable, and the noise induced by Karman vortex street is reduced. The blade is made of metal and formed into a one-piece blade or a split-type blade consisting of a main blade body made of metal and a rear end member made of metal other than that of the main blade body, the rear end member being fixed to the rear end of the main blade body, dentation being formed in the trailing edge part of the blade along the length thereof, the dentation being shaped in a serration of triangular teeth, of trapezoidal teeth, or of sawteeth, the ratio(h/&dgr;) of the tooth height h to the thickness &dgr; of the boundary layer developed on the surface of the blade is: h/&dgr;=1.0˜10.0, and the ratio (h/p) of the tooth height h to the pitch p is: h/p=0.5˜5.0.

    Abstract: Forged compressor scrolls are made of an aluminum-silicon alloy consisting essentially of 8.5 to 10.5% silicon and not more than 0.2% antimony wherein the silicon is present as eutectic particles having an average particle diameter in the range of 2 to 8 .mu.m, the particles being uniformly dispersed with a degree of dispersion in the range of 10,000 to 30,000 particles/mm.sup.2. Such scrolls are free of internal defects and have reduced susceptibility to seizing and cracking combined with high abrasion resistance.
