| 20120014827 | Corrosion Resistant Metallurgical Powder Compositions - Provided are corrosion resistant metallurgical powder compositions, corrosion resistant compacted articles prepared from metallurgical powder compositions, and methods of preparing the same. Corrosion resistant metallurgical powder compositions include as a major component, an iron-based powder and, as a minor component, alloy additives that include chromium, and carbon. Upon compaction and sintering, the iron-based powder and alloy additives form a dual phase alloy system. The dual phase alloy system is denoted by an admixed martensite and ferrite microstructure. This unique microstructure results in beneficial physical properties, such as for example, high strength, hardness, and ductility, impact energy, and fatigue endurance, while maintaining resistance to corrosion. | 01-19-2012 |
| 20110283832 | COMPOSITIONS AND METHODS FOR IMPROVED DIMENSIOINAL CONTROL IN FERROUS POWDER METALLURGY APPLICATIONS - Iron-based powder metallurgical compositions including both iron-copper prealloy and copper powder are described. These compositions, when compacted and sintered, result in compacts having good dimensional consistency. | 11-24-2011 |
| 20110274577 | COMPACTION METHODS - The present invention is directed to improved compaction techniques for use in powder metallurgical applications using lower temperatures and pressures than are traditionally used in the field. | 11-10-2011 |
