Achieving High Damping Capacity in Oxygen‐Enhanced BCC Zr‐Hf‐Ti‐Nb Multi‐Principal‐Element Alloys with Low Young's Modulus

Advanced Science, EarlyView.
A series of oxygen‐enhanced Zr‐Hf‐Ti‐Nb MPEAs with high strength and outstanding damping capacity are developed through tailoring the BCC structural stability by an elaborate composition regulation. Strengthening mechanism for high strength and damping mechanism related to various Snoek‐type relaxations reveals that the existence of multiple separate O‐
