MACHINABLE GRADE FERROUS POWDER BLEND AND SINTERED COMPACT CONTAINING BN.

摘要

The machinability characteristics of P/M ferrous sintered compacts are improved when the compact is prepared from a ferrous powder having a maximum particle size less than about 300 microns, and from at least about 0.01 weight percent of a boron nitride powder comprising agglomerates of irregular-shaped, submicron particles.
