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.
