Abstract
A torsionally reacting spring, such as a helical spring, a torsion bar, or a torsion tube, requires the ability to torsionally deform elastically during service and return to its original, undeformed shape. The torsionally reacting spring is made of a bulk-deforming amorphous alloy which may be cooled from the melt at a cooling rate of less than about 500.degree. C. per second, yet retain an amorphous structure. A preferred bulk-solidifying amorphous alloy has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel, plus incidental impurities, the total of the percentages being 100 atomic percent.
