Abstract
A method of sinter fitting a powder metal compact around a core forms a composite component. By exploiting the shrinkage associated with the sintering of a powder metal compact, a sintered powder metal section may be dimensionally shrunk onto a core to create a mechanical interference fit between a core section and a sintered powder metal section. This method may be used to join materials such as aluminum and steel together, which traditionally have been difficult to join to one another.
