摘要： A brake drum includes a ring-shaped drum body (13), and a friction member (16) secured to the inner circumferential surface (18) of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum can be reduced in weight as a whole. Further, because the friction member, having projecting portions (17a) formed on its outer periphery (17), is cast-enveloped by molten metal of the Al alloy, the friction member and the drum body can be firmly fastened together. Thus, even when a great braking force is applied to the drum brake, the friction member can be prevented from being undesirably detached from the drum body.

摘要： A cast-bonding process includes a magnesium coating step and a magnesium nitride-forming step. The magnesium-coating step is carried out by supplying gasified magnesium into a mold in which a cast-in insert formed from an aluminum alloy, or an aluminum-based composite material is set, so that magnesium may coat the insert. The magnesium nitride-forming step is carried out by supplying nitrogen gas into the mold so that the coating magnesium and nitrogen gas may react to form magnesium nitride. Then, a molten aluminum alloy is poured into the mold for cast-bonding the insert.

摘要： An aluminum casting process using a casting mold in which after the cavity (25) is filled with an inert gas, magnesium is introduced in to the cavity to have a magnesium layer (58a) deposited on the cavity wall. Then, nitrogen gas is introduced into the cavity to form magnesium nitride (58b) on the surface of the magnesium layer after the cavity wall is heated to a specific temperature. Then, molten aluminum is supplied to have an aluminum casting molded, while the surface of the molten aluminum (39) is reduced with magnesium nitride. This makes it possible to form magnesium nitride within a short time and decrease the amount of nitrogen gas as required.

摘要： An aluminum casting method includes the step of applying in advance a mold release agent including magnesium to a mold surface. Thereafter, a nitrogen gas is injected into a cavity to cause reaction between the magnesium in the surface of the mold release agent and the nitrogen gas, thereby forming magnesium nitride. Since the nitrogen gas reacts only with the magnesium exposed in the surface of the mold release agent, the forming time of the magnesium nitride is reduced and also the amount of nitrogen gas used is reduced.

摘要： A method for injection molding a metallic material is disclosed in which an injecting material comprised of a half-solidified metallic material and a molten metallic material is injected into a cavity of a die from an injection cylinder through a gate thereof. A non-product portion remaining at the gate of the die is separated from a product portion while it is still hot. The separated high-temperature non-product portion is press-formed into a billet in the injection cylinder. Utilization of heat from the injecting material in melting the high-temperature billet enables reuse of the non-product portion remained at the gate and reduction of heat energy required in melting the billet.

摘要： Disclosed is a method for producing metal-ceramic composite materials, comprising setting a porous shaped material of an oxide-type ceramic and magnesium in a furnace; establishing a rare gas atmosphere, subliming the magnesium under heat, and dispersing the resulting magnesium vapor into the porous shaped material all within the furnace; introducing nitrogen gas into the furnace, causing the gas to react with the sublimed magnesium to form magnesium nitride (Mg.sub.3 N.sub.2), bringing the magnesium nitride into contact with the oxide in the surface of the porous shaped material thereby reducing the oxide and exposing metal atoms at the material surface, and thereafter infiltrating a molten metal into the porous shaped material.

摘要： A method of feeding a blank (31) by cutting a billet (11) for plastic working includes the steps of superimposing a plurality of annular members (15 to 18) having a coefficient of linear expansion smaller than that of the billet and an inside diameter slightly greater than the outside diameter of the billet on one another to assemble a tubular jig (12), inserting the billet into the assembled jig, heating the billet and the jig to a temperature at which the billet is half-molten, and cutting the billet into at least one blank by moving the annular members adjacent to one another in opposite directions. The cutting of the billet does not need a cutting tool, thus causing no wear of blades, and thereby allowing reduction in production cost. The billet can be cut into a plurality of pieces at a time, increasing productivity. Since the blanks can be fed together with the annular members, there is no need to reheat the blanks, providing increased productivity.
