摘要
An alloy disc includes a hub portion, a rim portion and a web portion disposed between the hub portion and the rim portion. The disc includes a fine grain structure substantially in a first region of the disc and a coarse grain structure substantially in a second region of the disc. The fine grain structure may be in the hub portion of the disc, and the coarse grain structure may be in the rim portion of the disc. The coarse grain structure may extend a greater distance radially inwardly from the rim portion into the web portion on the first axial end of the disc than on the second axial end of the disc. The fine grain structure may extend a greater distance radially outwardly from the hub portion into the web portion on the second axial end of the disc than on the first axial end of the disc.
