    摘要： To prepare an aluminum matrix particle composite alloy, a molten metal, mainly composed of aluminum, containing ceramic particles is disintegrated by atomization, to prepare atomized powder. The atomized powder is mechanically ground/reflocculated with a ball mill or the like, to prepare mechanically ground/reflocculated powder containing ceramic particles of not more than 8 .mu.m in maximum diameter and not more than 3 .mu.m in mean particle diameter. The mechanically ground/reflocculated powder is then warm-formed/solidified. Alternatively, an aluminum alloy molten metal containing dispersed particles is disintegrated by atomization, and thereafter the powder containing the dispersed particles of not more than 20 .mu.m in mean particle diameter is warm-formed/solidified by powder forging. Thus, it is possible to obtain an aluminum matrix particle composite alloy in which extra-fine ceramic particles are homogeneously distributed without segregation.

    摘要： An aluminum-chromium based alloy which has a high strength, an excellent heat resistance, corrosion resistance, and a light weight contains 10 to 25 atomic percent of Cr and 0.1 to 5.0 atomic percent of Fe and/or Ni. The total content of Cr, and Fe and/or Ni is not more than 30 atomic percent The remainder substantially consists of aluminum. The aluminum-chromium based alloy partially or entirely exhibits and amorphous state by X-ray diffraction. This aluminum-chromium based alloy is obtained by first preparing a powder by a rapid solidification method, then converting the powder raw material to an amorphous powder by performing a mechanical grinding treatment thereon, and then hot working the amorphous powder.

    摘要： In a valve gate device and an injection mold provided with the valve gate device, a movable pin moves easily in order to properly open and close the gate, thereby preventing damage to the valve gate device and the mold. A movable pin 17 is made more durable by using a harder material for the movable pin 17 than for a valve body 11, and a slight distance can be maintained between the movable pin 17 and the valve body 11 by making the thermal expansion coefficient of the movable pin 17 smaller than that of the valve body 11, so that the problem of initial improper movement of the movable pin 17 can be eliminated.

    摘要： A connecting rod as a shaft clamping member includes a rod member and cap, each of which has mating faces at circumferentially opposite ends of a semi-circular recess and which are fastened to each other by bolts by matching the opposed mating faces to each other to define a crank pin hole by the two semi-circular recesses. The rod member and the cap are forgings formed from an aluminum alloy and simultaneously produced by forging powder preforms of the rod member and cap in a cavity having the desired shape of the connecting rod. After forging, the opposed mating faces have an infinite number of recesses and projections which are formed from the flow of the material during the forging and which are in a matched and fitted relation to each other. Thus, any misalignment between and in a direction parallel to the mating faces can be prevented to avoid the generation of a situation that only the rod member receives a stress. This achieves a prolongation in the life of the connecting rod of the aluminum alloy. The composition of the most desirable aluminum alloy includes, by weight, 7% .ltoreq.Fe
