Gradient and lamellar heterostructures for superior mechanical properties

Xiaolei Wu et al.

Summary: Heterostructured materials are a novel class of materials with mechanical properties superior to their conventional counterparts. The two most studied heterostructures are grain-size gradient structure and heterolamellar structure, which produce heterogeneous deformation during tensile deformation, enhancing strength and retaining ductility through HDI stress.

Strain partitioning enables excellent tensile ductility in precipitated heterogeneous high-entropy alloys with gigapascal yield strength

Feng He et al.

Summary: A Ni2CoCrFeTi0.24Al0.2 HEA was developed with a yield strength of approximately 1.3 GPa and tensile elongation of 20% through single-step heat treatment. The excellent strength-ductility combination is attributed to the grain scale heterogeneous structure with L1(2) precipitates ranging from 10 to 100 nm. Additionally, the efficient hetero-deformation induced strain hardening effect allows for the good ductility of the HEA.

Deformation induced hcp nano-lamella and its size effect on the strengthening in a CoCrNi medium-entropy alloy

Yan Ma et al.

Summary: Deformation-induced hcp nano-lamellae were observed in the CoCrNi medium-entropy alloy under high strain rate and cryogenic temperature, leading to higher hardness compared to room temperature-deformed samples. Molecular dynamics simulations revealed that both phase strengthening and extra interface strengthening contribute to the overall strengthening, with the interface strengthening always stronger. Samples with smaller interspacing of hcp nano-lamellae showed higher strength due to increased density of phase boundaries and newly formed twin boundaries.

Chunduo Dai et al.

Summary: This study thoroughly investigated the impact of annealing treatments on the microstructure, mechanical properties, and corrosion behavior of FeCoCrNiMo0.1 alloy. The results showed that annealing treatments significantly affected grain size, leading to different mechanical properties and deformation characteristics. Alloys annealed at 900 degrees C for 30 min and 60 min exhibited improved mechanical properties and corrosion resistance.

Static recrystallized annealing treatment-induced strength-ductility trade-off in cold-rolled Co36Fe36Cr18Ni10 multi-principal alloy

Hao Wang et al.

Summary: A new multi-component Co36Fe36Cr18Ni10 alloy was developed with outstanding ductility and mechanical properties, achieved through careful processing to create fine grains, stacking faults, dislocations, and nanoscale annealed twins in the microstructure. Annealing at 700 degrees Celsius improved the microstructure and enhanced the mechanical properties, balancing the trade-off between strength and ductility effectively. This study demonstrates that heterogeneous designs for structural materials can be achieved through simple low-temperature annealing processes, reducing energy consumption while improving performance dimensions spanning from submicron to nanoscale.
