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.
摘要翻译：通过切割用于塑性加工的坯料（11）来进给坯料（31）的方法包括以下步骤：将具有小于坯料的线性膨胀系数的多个环形构件（15至18）重叠，并且内径稍微大于坯料的外径，以组装管状夹具（12），将坯料插入组装的夹具中，将坯料和夹具加热至坯料半熔融的温度，并切割通过沿相反的方向移动相邻的环形构件，坯料进入至少一个坯料。坯料的切割不需要切削工具，因此不会造成刀片磨损，从而能够降低生产成本。一次可以将坯料切成多个片，提高生产率。由于坯料可以与环形构件一起进料，所以不需要再加热坯料，从而提高生产率。

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 into 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： 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： For forming a preform of composite material, such as aluminum-based composite material (MMC) by using friction during the forming thereof, ceramic reinforcement, such as Al2O3 and binder are prepared, and the prepared reinforcement and the silanor group binder are put into a die for press forming. During the forming, polycondensation occurs due to frictional heat generated between the fibrous or grain-like particles of the reinforcement and the silanor group binder to harden it, thereby obtaining a preform in which the particles of the reinforcement are fixedly connected to one another.

摘要： A method for producing an aluminum alloy composite material comprises disposing in a mold, in sequence from bottom to top, an infiltration enhancer containing Mg, a preform and an aluminum matrix alloy ingot, and then inserting the mold into an atmospheric furnace. The interior of the atmospheric furnace is then turned into an argon atmosphere. Thereafter, the internal temperature of the furnace is raised to a first predetermined temperature which is maintained for a given period of time so that the infiltration enhancer sublimates to permit the Mg component thereof to infiltrate into the preform. The atmosphere inside the furnace is then turned from the argon atmosphere into a nitrogen atmosphere. Thereafter, the internal temperature of the furnace is raised to a second predetermined temperature higher than the first predetermined temperature and maintained for a given period of time so that the aluminum matrix alloy ingot melts to permit the aluminum matrix alloy to spontaneously infiltrate into the preform. The interior of the furnace is then cooled to thereby produce an aluminum alloy composite material of high-quality.

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： 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.
