 | Aluminum-based P/M hand forgings and extrusions in two Al-Zn-Mg-Cu alloys have been studied to evaluate the effects of powder processing variations on forging quality and properties and extrusion properties. High quality hand forgings with high strength and ductility have been produced directly from hot pressed aluminum powder compacts without an intermediate extrusion operation. The processing conditions leading to maximized hand forging properties are: Cold press to at least 70% green ... |

|
| The program consisted of a study to establish powder requirements and processing procedures needed to produce AF95 powder metallurgy disk components having more consistent mechanical properties than conventional forgings at costs competitive with conventional methods. The study was based upon the concept of controlling carbon content as well as oxygen as the means for achieving these objectives. The study was conducted in two phases: Phase 1 - Determination of Powder ... |

|
| An investigation of oxide dispersion strengthening of oxidation resistant FeCrAlY alloys was conducted using both coarse and fine metal powder approaches. The most successful method involved preoxidizing and extruding Fe-25Cr-4Al-1Y (2541) coarse atomized powders. A detailed thermomechanical processing (TMP) study of this material showed that 2000F tensile and stress rupture properties varied widely with rolling-heat treating schedules. Yield and tensile strengths at 2000F were from 1 to 4.5 times the ... |

| Powder-metallurgy Fe-P alloys contg. 0.7, 0.8, 0.9, and 1.0 wt. % P were prepared by pressing under 35-40 kilonewtons/sq cm and sintering in a protective atmosphere at 1060 plus or minus 10C for 1 hr., applying during sintering a pressure of 150-200 newtons/sq cm. Friction characteristics were determined by friction against dry cast iron with hardness of 1.2-1.5 kilonewtons/sq cm and comparing with similar results obtained with the powder-metallurgy material ... |
