<P>PROBLEM TO BE SOLVED: To provide an alloy in which the glass formability is excellent, the compatibility with a living body is improved; and to provide especially an alloy that does not emit nickel even if contacting with a body fluid. <P>SOLUTION: The alloy includes an amorphous phase and is shown by general formula [Zr<SB POS="POST">x</SB>(Fe<SB POS="POST">100-x</SB>)<SB POS="POST">a</SB>(Al<SB POS="POST">y</SB>G<SB POS="POST">100-y</SB>)<SB POS="POST">100-a</SB>]<SB POS="POST">100-b</SB>Z<SB POS="POST">b</SB>. In the formula, a, b, x, and y are a real number indicating an atomic percent; 70≤a≤90, x≥50, y>0, 0≤b≤6 are satisfied; G denotes at least one element chosen from the group consisting of platinum and palladium; Z is a component comprising at least one element; and all component of G and Z are each different and are not zirconium, iron, and aluminum; and the alloy does not substantially includes copper and nickel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
