摘要： Disclosed herein is a process for producing a high strength aluminum-based alloy powder comprising mixing Al or Al alloy powder with an Al--T--X alloy powder, wherein T is at least one selected from the group consisting of V, Cr, Mn, Fe, Co, Ni, Cu, W, Ca, Li, Mg and Si; X is at least one selected from the group consisting of Y, Nb, Hf, Ta, La, Ce, Sm, Nd, Zr and Ti or Mm; and mechanically alloying the formed powder mixture. The aluminum-based alloy powder is excellent in workability and reliability by virtue of its high strength stability in the temperature range of from room temperature to an elevated temperature, its excellent ductility in the same temperature range and its low thermal expansion coefficient in the same temperature range.

摘要： A superplastic aluminum-based alloy material consisting of a matrix formed of aluminum or a supersaturated aluminum solid solution, whose average crystal grain size is 0.005 to 1 .mu.m, and particles made of a stable or metastable phase of various intermetallic compounds formed of the main alloying element (i.e., the matrix element) and the other alloying elements and/or of various intermetallic compounds formed of the other alloying elements and distributed evenly in the matrix, the particles having a mean particle size of 0.001 to 0.1 .mu.m. The superplastic aluminum-based alloy material is produced from a rapidly solidified material consisting of an amorphous phase, a microcrystalline phase or a mixed phase thereof by optionally heat treating the material at a prescribed temperature for a prescribed period of time and then subjecting it to a single or combined thermomechanical treatment. The superplastic aluminum-based alloy material of the present invention is suited for superplastic working.

摘要： A golf club head made of a hollow metal comprising a face and a body, wherein at least the face is made of a rapidly solidified Al-based alloy having a high strength, high elasticity and light weight. This golf club head makes it possible to stroke a ball without elastic deformation of its face and also to fly the ball farther with the initial speed thereof maintained, by using the Al-based alloy at least in the face. In addition, the use of the Al-based alloy makes it possible to form a large head and a long shaft so that balls can be stroked to fly over a long carry in an accurate direction.
