    摘要: Forming a precipitation hardened composite material having reinforcing particles and precipitated intermetallic particles dispersed in the binder material may involve heat treating the hard composite material at a temperature above a solvus line for the binder material and below a melting point of the binder material and quenching the hard composite material to a temperature below the solvus line of the binder material. At least some of the precipitated intermetallic particles in the precipitation hardened composite material may have at least one dimension less than 1 micron. Such precipitated intermetallic particles may optionally be grown to larger sizes by heat treating the precipitation hardened composite material at a temperature below the solvus line of the binder material.

    摘要: A drill bit in which a cutting element support shoe is mounted to a drill bit member so that it covers a portion of a number cutting elements while leaving the cutting edges of cutting elements exposed to the formation. The drill bit member may include a bit body, blade, arm, or roller, for example. The drill bit member may include a recess into which the cutting element support shoe is received. Cutting element support shoe provides mechanical holding of the cutting elements within their pockets in addition to conventional brazing or other mounting techniques. Once installed, a hard facing material may be applied over the cutting element support shoe as appropriate for increased erosion resistance. In one embodiment, the cutting element support shoe is sized so that when mounted to the drill bit member it is elastically deformed, thereby providing additional cutter retaining force upon attachment.
