Abstract
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.
