Disclosed is a gear including a resettable metallic glass. The gear of the present disclosure includes, as a base material, a resettable metallic glass, wherein the resettable metallic glass includes at least one metal element selected from each of (a) the group consisting of Ti, Zr, and Hf and (b) the group consisting of Fe, Co, Ni, Cu, and Zn, and further includes at least one metal element to maximize the complexity in the thermodynamic enthalpy of mixing among constituent elements, thereby including multiple resetting cores in various atomic-scale cluster forms in an amorphous matrix, leading to a structure with maximized structural complexity.
A resettable gear, in which a resettable metallic glass comprises at least one metal element selected from each of (a) the group consisting of Ti, Zr, and Hf and (b) the group consisting of Fe, Co, Ni, Cu, and Zn, the ratio of the element of the element group (a) to the element of the element group (b) being 15 to 66.6 at. % to form an amorphous structure,
A method for manufacturing a resettable gear, the method comprising:
Parallel axis gears including spur gears, helical gears, and rack gears, intersecting gears including bevel gears and crown gears, and non-parallel and non-intersecting gears including screw gears, helical gears, worm gears, and strain wave gears, each of the gears being composed of a resettable metallic glass.
