Cryogenic strength-ductility synergy in Mg-6Gd-1Zn alloys with bimodal grain structure coupled with basal lamellar phase

Materials Research Letters
Achieving simultaneous strength and ductility at cryogenic temperature (CT) remains challenging for Mg alloys. An extruded Mg-6Gd-1Zn (wt.%) alloy with bimodal grain structure and basal lamellar phases exhibits anomalous strength-ductility synergy at CT.

Superior strain-hardening and strength-ductility synergy by hierarchical L12 phases in a highly (Al, Ti)-added medium-entropy alloy

Journal of Materials Research and Technology
A novel precipitate-strengthened Co–Cr–Ni medium-entropy alloy with a pure “FCC + L12” dual-phase structure is developed by adding a high concentration (6 at.%) of Al and Ti elements.

Gradient phase stability mediated by heterogeneous α-precipitation achieves yield strength-ductility synergy in TWIP β-Ti alloy

Journal of Materials Research and Technology
In this paper, a core-shell metastable β-Ti alloy was tailored with the heterogeneous distribution of α precipitations at grain scale to improve the yield strength (YS) of twinning induced plasticity (TWIP) metastable β-Ti alloy without sacrificing ...
