Brittle-ductile transition in vanadium
, 1958 Mechanical tests have been made on two grades of vanadium over a range of temperatures below 25°C to establish the existence of a brittle-ductile transition and the temperature range over which it occurs. Also, the effect of small amounts of metallic and

Architected Inverse Nacre Hydrogels With High Strength and Crack‐Insensitive Toughness
Advanced Science, EarlyView.Hydrogels hold promise for biomedical and engineering applications, yet their practical use is fundamentally limited by the strength‐toughness trade‐off and poor fatigue resistance. In this study, a bioinspired inverse nacre architecture constructed via a scalable thermo‐calendering process is introduced, which overcomes these classic limitations ...
