First claim
Opening claim text (preview).
The invention claimed is: 1. A timepiece component, comprising: a high-entropy alloy, wherein the high-entropy alloy is formed of multiple metallic elements forming a single-phase structure, and the high-entropy alloy satisfies formula Ta a Nb b Hf c Zr d Cr e , where a, b, c, d, and e are each a value independently ranging from 1 to 55 at. %. 2. The timepiece component according to claim 1 , wherein the high-entropy alloy comprises one or more interstitial elements selected from the group consisting of C, N, and B. 3. The timepiece component according to claim 1 , wherein the high-entropy alloy comprises one or more structural hardening elements selected from the group consisting of Ti, Al, Be, and Nb.
