Common strengthening strategies for casting aluminum alloys sacrifice ductility. Herein, the strength-ductility synergy of a rheo-diecasting semi-solid Al–Si–Mg–Cu–Fe–Sr alloy was tailored by optimizing the pouring temperature and subsequent heat treatment. The results demonstrated that with ...
Given the energy-efficient improvement and large safety factors, the attainment of high strength and high ductility in materials is arguably a vital requirement for most engineering applications. Unfortunately, these two properties are generally mutually exclusive, particularly in pure metals and alloys1,...
Realizing improved strength–ductility synergy in eutectic alloys acting as in situ composite materials remains a challenge in conventional eutectic systems, which is why eutectic high-entropy alloys (EHEAs), a newly-emerging multi-principal-element eutectic category, may offer wider in situ composite ...
The formation of the dominant //ED component was attributed to the preferential growth of DRXed grains with //ED as well as shear-stress-induced effect in the RBE technique. The gradient microstructure and abnormal texture simultaneously improved the strength and ductility of the RBE sample, with...
Strength–plasticity synergy enabled by lattice distortion In order to develop an alloy with both large lattice distortion and a stable lattice structure, we took into consideration the influence of large atomic size differences and electronic property variations. These factors contribute to the formation...
Abstract A dual-phase (DP) Ni–66.7%Co alloy with an average grain size of 16 nm was fabricated by electrodeposition. It exhibited an ultimate tensile strength of 1800–2080 MPa, together with an elongation to failure of 10–15% at room temperature. The remarkable ductility of this DP alloy...

The microstructure and mechanical properties of micro-alloyed Mg-0.5 wt%Ce alloys are investigated systemically in this study. It shows that Mg-Ce binary system is very sensitive to extrusion temperature. On the one hand, the high tensile yield strength (TYS) of 343 MPa was obtained by ...
A combination of 1 to 1.2 GPa yield strength (21.3 % increase) with a total elongation of 20 to 10 % was achieved. The chosen methodology was efficient in the design of a novel MPEA with an improved strength-ductility synergy.doi:10.1016/j.matdes.2020.109315Fabian Kies...
introduced phase heterogeneity in Fe50Mn30Co10Cr10 via the transformation-induced plasticity (TRIP) mechanism, leading to the substantially enhanced strength-ductility synergy with the tensile elongation >70% [9]. Pan et al. constructed a heterogeneous gradient dislocation cell structure (GDS) in Al...
