Sample text

However, the vast majority of work to date has been on the third type, which is generally produced using a P/M approach, and this article only considers this type of nanostructured material. A schematic representation of a nanostructured crystallite material is shown in Fig. 9 (Ref 27). The large fraction of atoms located in the grain boundary regions results in novel processing possibilities and enhanced combinations of mechanical, physical, and magnetic behavior compared to materials, with a more conventional grain size (>1 m).

A slightly lower amount is used in Japanese automobiles (Table 2) (Ref 6), but automotive application of P/M parts is still the dominant use in Japan as well (Fig. 2). The growth of P/M parts in automobiles is due to increased use of P/M components in engines, transmissions, brakes, airbags, and other complex parts. Emerging automotive applications are also described at the end of this article. 6 Fig. 1 Growth of powder metallurgy in Ford automobiles Fig. 2 Annual production amounts for P/M parts in Japan.

The higher green strength provides an opportunity to machine the P/M part in the green state. This capability is critical in the use of highperformance alloy systems that achieve high hardness in the as-sintered state. 4 g/cm3, which is considerably higher than cold-compacted-and-sintered P/M parts. 6% lubricant. 6% lubricant. Warm compaction, although applicable to all ferrous material systems, produces the greatest benefits when coupled with high-performance compositions such as diffusion-alloyed steels or molybdenum-prealloyed steels.
