Abstract:
1. A method of forming a remateable cracked titanium powder base alloy connecting rod, the method comprising the steps of: (a) providing a body containing titanium powder base alloy, said powder base alloy having an average particle size of about 1-20 microns, a mean aspect ratio of about 5 to 300, and specific surface area of at least about 25 m (b) providing a mold for a connecting rod, said mold defining a connecting rod having a large bore therein for use as a large bearing and a small bore for use as a small bearing, said bores connected by an arm member; (c) adding said powder base alloy to said mold; (d) compressing said powder base alloy to form a preform; (e) sintering the preform to form a titanium connecting rod; and (f) fracturing a cap portion along a fracture plane in a wall defining said large bore to provide a cap portion having cracked surfaces which permit substantially exactly rematching said cracked surfaces for securing said large bearing to a bearing surface of an engine crank.
