摘要： A raw material for powder metallurgy contains at least 0.5 vol % and at most 10 vol % of alumina powder of which the sieve fraction with a sieve opening of 30 .mu.m is at most 0.1 wt %, and a remaining part of aluminum alloy powder. The moisture content of the alumina powder is at most 0.15 wt. % with respect to the alumina powder. Agglomeration of particles is thereby minimized or avoided. Highly reliable raw material for powder metallurgy having superior fatigue strength, impact resistance and wear resistance can be obtained. A method of preparing such a mixed powder raw material involves air classifying the powder materials, dry ball mixing the materials, and then annealing the mixed powder.

摘要： An aluminum alloy structural member is crystalline. In producing this aluminum alloy structural member, a procedure is employed which includes forming a green compact by use of aluminum alloy having an amorphous phase, and subjecting the green compact to a powder forging technique. An aluminum alloy powder exhibiting an exotherm E smaller than 20 J/g at the time of the crystallization of the amorphous phases is used. By setting the exotherm E in such a range, cracking of the green compact due to a degassing can be avoided, even if the green compact is rapidly heated in a temperature-rising or heating course.

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： 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
