Abstract
A forged composite inner race for a constant velocity joint is forged from a composite preform compact including a first powder metal material and a second powder metal material. The forged composite inner race includes a plurality of ball tracks formed on an outer section of the forged composite inner race with corresponding lands between adjacent ball tracks and an axially-extending splined opening formed in an inner section of the forged composite inner race. The outer section comprises the first powder metal material in a higher concentration than the second powder metal material and the inner section comprises the second powder metal material in a higher concentration than the first powder metal material.

A forged composite inner race for a constant velocity joint forged from a composite preform compact including a first powder metal material and a second powder metal material, the forged composite inner race comprising:
- a plurality of ball tracks formed on an outer section of the forged composite inner race with corresponding lands between adjacent ball tracks, the outer section comprising the first powder metal material in a higher concentration than the second powder metal material;
- an axially-extending splined opening formed in an inner section of the forged composite inner race, the inner section comprising the second powder metal material in a higher concentration than the first powder metal material;
- and
- a variable boundary profile formed between the outer section and the inner section in which a radial distance from an axis of rotation of the forged composite inner race to the variable boundary profile varies over an axial length of the forged composite inner race.
