Abstract
Billets are produced from powdery alloys by a process which comprises densely packing in a can a powdery metal or alloy easy of plastic working and a powdery alloy difficult of plastic working in that order, sealing hermetically the can and thereafter degassing the same; or a process which comprises densely packing a powdery alloy difficult of plastic working in a can and, then, densely packing a powdery metal or powdery alloy easy of plastic working in the can to make the powdery metal or alloy into a lid of the can, wherein the powdery alloy easy of plastic working is coarse powder, while the powdery alloy difficult of plastic working is fine powder, and the powdery alloy is a rapidly solidified powdery alloy comprising an Al-base, Mg-base, Ni-base, Ti-base or Fe-base alloy. The billets obtained by the above process can be easily subjected to plastic working to provide worked articles having with excellent mechanical characteristics, such as high strength and high hardness, without deteriorating the properties of the starting powder materials.
