    • PURPOSE: To provide certain Zr-based amorphous alloys that can be made from commercially available raw materials and that can be conventionally cast to a substantially greater thickness while retaining a bulk amorphous microstructure. CONSTITUTION: The amorphous alloy is represented by the atomic formula: (Zr,Hf)a(Al,Zn)bTie,Nbf,TagYh(CuxFey(Ni,Co)z)d, wherein a ranges from 45 to 65 atomic %, b ranges from 5 to 15 atomic %, e and f each ranges from 0 to 4.5 atomic %, g ranges from greater than 0 to 2 atomic %, h ranges from 0 to 0.5 atomic %, and the balance is d and incidental impurities and wherein e+f+g ranges from 3.5 to 7.5 atomic %, d times y is less than 10 atomic %, and x/z ranges from 0.5 to 2, wherein g ranges from 1 to 2 atomic %, wherein h ranges from 0.1 to 0.4 atomic %, wherein Ti and Nb are both present and e+f is less than about 4 atomic %, and wherein e=1.5 atomic %, f=1.5 atomic % and g=1.5 atomic %. The amorphous alloy consists essentially of, in atomic %, about 54 to about 57 % Zr, 0 to about 4 % Ti, 0 to about 4 % Nb, greater than 0 to about 2 % Ta, about 8 to about 12 % Al, about 14 to about 18 % Cu, about 12 to about 15 % Ni, and 0 to about 0.5 % Y.
    • 目的:提供某些可由市售原料制成的Zr基非晶态合金,并且可以通常将其浇铸到基本上更大的厚度,同时保持块状无定形微观结构。 构成:非晶合金由原子式:(Zr,Hf)a(Al,Zn)bTie,Nbf,TagYh(CuxFey(Ni,Co)z)d表示,其中a在45至65原子%的范围内,b 范围为5〜15原子%,e和f各自为0〜4.5原子%,g为0〜2原子%左右,h为0〜0.5原子%,余量为d,附带杂质, e + f + g范围为3.5〜7.5原子%,d倍y小于10原子%,x / z为0.5〜2,g为1〜2原子%,h为0.1〜0.4 原子%,其中Ti和Nb都存在,e + f小于约4原子%,其中e = 1.5原子%,f = 1.5原子%,g = 1.5原子%。 非晶合金基本上由原子%,约54-约57%的Zr,0-约4%的Ti,0-约4%的Nb,大于0-约2%的Ta,大约8-大约12%的Al, 约14至约18%的Cu,约12至约15%的Ni和0至约0.5%的Y。
