PCT No. PCT/JP91/00336 Sec. 371 Date Nov. 27, 1991 Sec. 102(e) Date Nov. 27, 1991 PCT Filed Mar. 13, 1991 PCT Pub. No. WO91/14013 PCT Pub. Date Sep. 19, 1991.An aluminum-chromium based alloy which has a high strength, an excellent heat resistance, corrosion resistance, and a light weight contains 10 to 25 atomic percent of Cr and 0.1 to 5.0 atomic percent of Fe and/or Ni. The total content of Cr, and Fe and/or Ni is not more than 30 atomic percent The remainder substantially consists of aluminum. The aluminum-chromium based alloy partially or entirely exhibits and amorphous state by X-ray diffraction. This aluminum-chromium based alloy is obtained by first preparing a powder by a rapid solidification method, then converting the powder raw material to an amorphous powder by performing a mechanical grinding treatment thereon, and then hot working the amorphous powder.
