Powder Metallurgy (PM) is a process for manufacturing components through. compaction of blended metal power followed by a sintering heat treatment. to achieve full density. Alternative to casting...
• Performance Characteristics of a Newly Developed Cost-Effective Cr-Ni Prealloyed Steel Designed to replace Fe-Ni Steels
  and excellent properties, but require careful sintering and heat treatment. The purpose of this paper will be to demonstrate the properties achievable with a new prealloyed Cr-Ni steel (Astaloy CMN) that is suitable for sintering in endogas and for conventional atmosphere heat treatment. The heat treated...
• Novel Manufacturing Technique Produces Parts Lighter and Stronger than Aluminum
  Magnesium injection molding (MAG) shapes parts out of magnesium alloy in a semifluid state, without the need of binders, resins, or sintering. This gives the relatively new technique an environmentally friendly tag. MAG is a socalled "thixomolding" process -- the name comes from the word...
• Porous-Metal Bearings
  sintering, the bearing must be sized to the specified dimensions. Sizing reduces interconnected porosity and produces greater strength, lower ductility, and a smoother finish. The most common porous bearing material. It contains 90% copper and 10% tin. These bearings are wear resistant, ductile...
• Fused Depostion Modeling: A Technology Evaluation
  author, published in Time Compression Technologies; August, 2002 filled this knowledge gap, from a user perspective, for three technologies: Stereolithography (SLA), Selective Laser Sintering (SLS) and PolyJet. To add to this body of information, another leading technology, fused deposition modeling...
• The nuts and bolts of ceramic fasteners
  and there is no need to adjust molds. A dewaxing process — sorry, trade secret — removes most of the wax and opens the material's porosity. We burn the rest of the wax out, then fire the part to 1,650°C, sintering it. The uniform density leads to uniform shrinkage in all dimensions. Between removing...
• Smaller-but-better permanent magnets
  at lower temperatures to improve the magnetic properties. Because of shrinkage and warpage during the sintering process, powder-metallurgy magnets must be produced in larger shapes and then ground to their final size. In the rapid-quenching process, molten NdFeB alloy is ejected onto a chilled...
