Patent number: 5549151Abstract: The present invention relates to the formation of bodies having graded properties. Particularly, the invention provides a method for forming a metal matrix composite body having graded properties. The graded properties are achieved by, for example, locating differing amounts of filler material in different portions of a formed body and/or locating different compositions of filler material in different portions of a formed body and/or locating different sizes of filler materials in different portions of a formed body. In addition, the invention provides for the formation of macrocomposite bodies wherein, for example, an excess of matrix metal can be integrally bonded or attached to a graded metal matrix composite portion of a macrocomposite body. Moreover, if desired, it is possible to produce a metal matrix composite body with substantially the same properties throughout.Type: GrantFiled: December 12, 1994Date of Patent: August 27, 1996Assignee: Lanxide Technology Company, LPInventor: Chwen-Chih Yang
