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： 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

摘要： In a powder forging process, a heated green compact is placed in a stationary die and subjected to a press-forging carried out mainly to reduce the thickness thereof by cooperation of the stationary die with a movable die. The press-forging is performed at two pressing steps. After placement of the green compact into the concave molding portion of the stationary die, the pressing step were carried out. Thus, it is possible to produce a forged product having a high strength and a high toughness. A heated heat insulator also may be placed in the stationary die to provide a temperature-retaining effect to the green compact before and during pressing.

摘要： A powder preform of aluminum alloy powder is subjected to a heating treatment and then to a compacting and hardening process under a pressure to produce a structural member of aluminum alloy. The aluminum alloy powder used is one having a non-equilibrium phase which shows a calorific value C in a range of C.gtoreq.10 J/g at a temperature-increasing rate of 20 K./min in a differential scanning calorimetry. In the heating treatment, the average temperature-rising rate R.sub.2 from a heat-generation starting temperature Tx (K.) of the aluminum alloy powder to Tx+A (wherein A.gtoreq.30 K.) is R.sub.2 .ltoreq.60 K./min. Thus, the change of the non-equilibrium phase in the powder preform is uniformly performed. In addition, the average temperature-increasing rate R.sub.4 from a processing temperature Tw (K.-B) in the compacting and hardening process to Tw (wherein B.gtoreq.30 K., and Tw-B>Tx+A) is R.sub.4 .gtoreq.60 K./min. Thus, the oxidation of the powder preform is reliably prevented.
