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.

A method for forming a copper-infiltrated iron powder metal article comprises compacting and sintering a predominately iron powder to form an iron-base matrix that contains between about 1 and 7 weight percent nickel and about 0. 1 and 1. 2 weight percent phosphorus. A copper metal is infiltrated into pores within the iron-base matrix. The product article comprises between about 2. 0 and 23 weight percent copper infiltrant. Preferably, infiltration is carried out concurrently with sintering of the iron powder compact. The resulting product exhibits a particularly useful combination of mechanical properties, including high tensile strength and elongation.

A position adjusting system for adjusting the position of a seat n a vehicle and preventing movement of the seat resulting from external forces acting on the seat. The system includes a seat track fixable to the vehicle, a motor actuator, and a gear train engaged with the motor actuator. The seat track is adapted to cooperate with the seat track to convert movement of the motor actuator into movement of the seat track and the seat. A non-reversing clutch mechanism is coupled with the gear train and adapted to transfer torque from the motor actuator through the gear train to move the seat upon actuation of the motor actuator but locking upon torque being applied through the seat track, thereby preventing the external forces acting on the seat from moving the seat relative to the vehicle.

An exhaust treatment device includes an inner shell and an outer shell. Fibrous insulation is positioned within a flexible container. The insulation is compressed 30 to 80 percent by volume. The flexible container is sealed to maintain a compressed state of the insulation. The flexible container and the compressed insulation are positioned between the inner and outer shells of the exhaust treatment device.

A method is provided for producing an exhaust gas aftertreatment or acoustic device () having a maximum operating temperature T. The method includes the steps of providing a blanket () of silica fiber or alumina insulation material having a weight percentage of SiOor AlOof greater than 65%; calcining the insulating material by heating the blanket () so that all of silica fiber insulation material is raised to a temperature T greater than T; and securing the blanket () on the device () after the calcining step. The blanket is encapsulated in a covering prior to the securing step, and before or after the calcining step, with the covering between the blanket and the device being a selected one of foil, wire mesh, or siliconized fiber glass.
