Achieving high oxygen tolerance in Ti6Al4V: Copper-oxygen co-doping strategy for ultrahigh strength-ductility balance

Conventional α + β Ti6Al4V alloys lack sufficient strengthening mechanisms, limiting strength. While oxygen (O) offers a cost-effective strengthening route, exceeding ∼ 0.33 wt% causes significant embrittlement. Here, we explored how to efficiently utilize interstitial oxygen to enhance the mechanic...
