A metal powder for powder metallurgy according to the invention contains Co as a principal component, Cr in a proportion of 25 to 32 mass %, Ni in a proportion of 5 to 15 mass %, Fe in a proportion of 0.5 to 2 mass %, W in a proportion of 4 to 10 mass %, Si in a proportion of 0.3 mass % to 1.5 mass %, and C in a proportion of 0.05 mass % to 0.8 mass %, wherein when one element selected from the group consisting of Ti, V, Y, Zr, Nb, Hf, and Ta is defined as a first element, and one element selected from the group and having a higher group number in the periodic table than that of the first element or having the same group number as that of the first element and a higher period number than that of the first element is defined as a second element, the first element is contained in a proportion of 0.01 to 0.5 mass %, and the second element is contained in a proportion of 0.01 to 0.5 mass %.

A bone cutter for use within the intramedullary canal is described. The bone cutter comprises a frusto-conical cutting head that extends to a barrel portion for attachment to a drive shaft. The cutting head comprises a plurality of spaced apart blades having a tissue cutting edge that extends radially from the exterior surface of the cutting head. The plurality of blades are arranged at prescribed angular relationships that are designed to increase cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.

A mold assembly includes a first mold part having guide passages defined therein. Protruding members are each movably received in a first portion of a respective guide passage to extend selectively in and out of the mold cavity. At least some of the protruding members are movable along different directions from one another. Cables are each connected to one of the protruding members and extend through a linear second portion of the respective guide passage and out of the first mold part. An actuator is connected to the cables and movable relative to the first mold part between an extended position and a retracted position. In the extended position, each protruding member protrudes into the mold cavity. In the retracted position, each of protruding member is retracted out of the mold cavity and contained within the respective guide passage. A guide element and a method of molding are also discussed.

A molding composition contains a powder, a wax, an adhesive component, a molding component, and a plasticizer, in which a melt flow rate of the adhesive component at 190° C. is 200 g/10 min or more, and a density of the plasticizer is 1.0 g/cm.sup.3 or less.

A method for producing a high temperature component includes a shaping step of shaping a powder compact of a desired high temperature component shape using a specific powder shaping method, from an alloy powder of γ′ precipitation strengthening-type Ni-based alloy, and a crystal grain coarsening step of coarsening a crystal grain size of the powder compact by heat treatment, wherein the powder compact contains 0.002% or more and 0.07% or less of C, and 5.40% or more and 8.40% or less of Al+Ti by mass percentage.

A load absorbing system that may include a rotor blade retention system is provided. The load absorbing system may include a block, a first retainer plate, and a deformable core. The block may be selectively positioned alongside a dovetail groove. The block may have a first face directed away from the blade root and an axially-spaced second face directed toward the blade root. The first retainer plate may be attached to the second face of the block and axially positioned between the block and the axially-directed surface of the blade root. The deformable core may be positioned between the block and the first retainer plate.

A method for manufacturing a cutting tool (10) with lubrication orifices of complex shapes, including the steps of: producing a polymer insert (20), overmoulding a body of the cutting tool (10) with the polymer insert (20) by injecting into a mould, removing the polymer insert (20), so as to form in the body of the cutting tool (10) lubrication orifices, the shape whereof is complementary with that of a part of the insert (20), machining the body of the cutting tool (10) on an active part thereof, and depositing an abrasive coating on a surface of the active part of the body of the cutting tool (10).
