Abstract
A sulfurous, metallic glass forming alloy and a method for the production thereof are described.
Claims11
A sulfurous metallic glass forming alloy that has the following formula:
- (Ti, Zr, Nb, Hf, Fe(1), Aa1)aPdb(Cu,Ni)c(V,Mo,Ta,W)d(Co,Cr,Fe(2))e,(Mn,Al,In,Ga,Ag,Si,Ge)fSngBeh(B,C)i(O, H, N)j(P,Sx1)x (I)
- in which:
- a=0%-approx. 15% by weight or approx. 30%-approx. 90% by weight,
- b=0%-approx. 68% by weight, and
- a+b=approx. 30%-approx. 97% by weight,
- wherein, when a=0%-approx. 15% by weight, b=approx. 35%-approx. 68% by weight, A is one or more elements in the group of rare earths (lanthanide+yttrium), wherein a1/a=0-approx. 1/10,
- c=0%-approx. 65% by weight
- d=0%-approx. 15% by weight
- e=0%-approx. 15% by weight
- f=0%-approx. 15% by weight
- g=0%-approx. 23% by weight
- h=0%-approx. 1% by weight
- i=0%-approx. 3.5% by weight
- j=0%-approx. 0.20% by weight,
- wherein, when b=0%, a and at least one of c and e>0%, and when a=0%-approx. 15% by weight, and b=approx. 35%-approx. 68% by weight, at least one of c, d, e, f, g >0% by weight, and
- Fe(1) and Fe(2) each stand for Fe, wherein Fe(2) is only present when a=0%, x=approx. 0.21%-approx. 9% by weight, when a=approx. 30%-approx. 90% by weight, and x=approx. 8%-approx. 16.5% by weight, when a=0%-approx. 15% by weight, and b>approx. 35% by weight, and
- x1/x≥approx. 1/10 to approx. 1, and the sum of all of the percentages by weight a+b+c+d+e+f+g+h+i+j+x+unavoidable impurities in trace amounts of elements not contained in the formula (I)=100% by weight,
- wherein at least when x1/x=approx. 1 and x=approx. 0.21%-approx. 1% by weight, alloys that contain Fe(1), Ni and Al are at least approx. 50% by volume amorphous.
