  • This work identifies a mechanism, termed dynamic plastic delocalization, that homogenizes deformation in FCC alloys, breaking the usual trade-off between monotonic strength and cyclic fatigue strength and enabling improved fatigue performance without loss of strength.

  • GRX-810, an oxide dispersion strengthened alloy, shows excellent structural performance above 1100°C and stability up to 1300 °C. Grain-size effects, additive manufacturing–induced anisotropy, and fine trigonal Y₂O₃ particles enhance creep resistance.

  • Research into engineering alloys is often driven by the need to simultaneously improve strength and toughness. Here, an equimolar CrCoNi medium-entropy alloy achieves an almost three times increase in yield strength without sacrificing toughness, attributed to a partially recrystallized microstructure.

  • The authors develop a new oxide-dispersion-strengthened NiCoCr-based alloy using a model-driven alloy design approach and laser-based additive manufacturing, showing how such designs can provide superior compositions using far fewer resources than previous methods.
