17. Steels commonly employed in structural and automotive applications are traditionally produced through processes such as casting, extrusion, and powder metallurgy [[105], [106], [107], [108]]. However, these conventional processes present challenges, such as slow cooling rates that induce coarse...
The high-temperature-precipitation behavior of a typical powder-metallurgy, gamma-gamma-prime, nickel-base superalloy (LSHR) was determined and used to develop and validate a quantitative fast-acting model. To this end, a series of experiments comprising supersolvus solution treatment followed by con...
The mechanical properties of PA compacts, fabricated using the ceramic mold process, for example the Ti-6Al-4V alloy, are at least at cast and wrought (ingot metallurgy) levels, includingfatigue behavior,Fig. 8.15.12The PA approach has been used to produce large and complex parts such as the...
The effectiveness of powder metallurgy as net-shape/near net-shape manufacturing technology is determined by the possibility of obtaining complex parts matching the required narrow tolerances. Sintering process determines change in volume of the green, and the related dimensional changes are significantly ...
Variations of Wf/Wm materials have been made via chemical vapor deposition [22,23] and powder metallurgy [24]. Initial tests of the Wf/Wm composites indicate the fibers provide additional toughness compared with standard W [22]. Show abstract Improved pseudo-ductile behavior of powder ...
Growth of primary titanium particles that are on average larger than 5 micron. Smaller particles are not ideally suitable for powder metallurgy and the relative size of the passivating oxygen layer equates to high levels of oxygen contamination. ...
We found that a high-strength sintered compact that can be used as an automobile high-strength sintered part can be produced at low cost using an alloy steel powder for powder metallurgy containing no nickel or copper and containing a relatively small amount of molybdenum by optimizing the chromi...
