Abstract
In accordance with the teachings of the present invention a structural member is formed by iron-phosphorous alloy powder having about 0.01 wt % to 1.2 wt % of phosphorous by weight of the powder. The powder is then pressed to the desired matrix density and copper infiltrated such that copper is present in the amount of 1.96 wt % to 23.08 wt %, by weight of the weight of the structural member. The final density of the structured member is in a range of 6.1 to 8.1 g/cc. The structural member formed using the sintered powder metal of the present invention has superior elongation (as much as 10.3% elongation), impact strength (159 N-m charpy unnotched), tensile strength (530 MPa), and modulus (166 GPa) as compared to standard density powder metal.
