Revealing the ultra-high high-temperature compressive mechanical properties and deformation mechanism of a heterostructured AlNp/ Al nanocomposite

Mengqi Jiang et al.

Summary: Heterostructured materials, such as the AlNp/Al composite studied here, have shown excellent mechanical properties at high temperatures. Isothermal compression tests revealed that the compressive strength of the AlNp/Al composite was maintained at room temperature and high temperatures (300-500 degrees C) throughout the deformation process. The combination of dispersive AlN nanoparticles, layered heterogeneous structure, and network structure prevented grain boundary softening and grain growth, as well as high temperature softening. The deformation mechanism of the composite was influenced by strain rate and temperature, with continuous dynamic recrystallization dominant at low strain rates and high temperatures, and dynamic recovery dominant at high strain rates and low temperatures. The strain rate sensitivity exponent (m) was used to assess the relationship between peak stress and deformation conditions, indicating that high temperatures and high strain rates should be avoided during hot deformation. This study sheds light on the microstructure design of high-strength heat-resistant aluminum matrix composites.

Crack-free and high-strength AA2024 alloy obtained by additive manufacturing with controlled columnar-equiaxed-transition

Xing Zhu et al.

Summary: In this study, highly dense and crack-free AA2024 samples were successfully additively manufactured by inoculation treatment of Zr-based metallic glass powders. The grain refinement in the LPBF-fabricated AA2024 alloy was achieved by the formation of Al3Zr particles, acting as heterogeneous nucleation sites. The complete routes for columnar-equiaxed transition were revealed by tailoring the concentration of nucleation particles and solidification conditions, leading to the formation of bimodal grain size distribution consisting of ultrafine grains and coarser grains.

Effect of remelting processes on the microstructure and mechanical behaviours of 18Ni-300 maraging steel manufactured by selective laser melting

Jun Song et al.

Summary: By remelting during the SLM process, the relative density of 18Ni-300 maraging steel can be increased and large-sized pores can be eliminated. Remelting can slightly coarsen the average grain sizes, increase the fraction of low-angle grain boundaries, and improve ductility and microhardness.

On the Sc induced solidification-heterogeneous microstructure in selective laser melted Al-5Mn alloys

Jinglin Lu et al.

Summary: The microstructure and mechanical properties of Al-Mn-Sc alloys fabricated by selective laser melting were studied. It was found that the precipitation sequence and Sc/Mn ratio were critical for controlling the grain and precipitate characteristics. The pre-precipitated Mn-bearing particles inhibited the formation of Al3Sc, resulting in a columnar grain structure, while the preferentially precipitated Al3Sc induced a bimodal grain structure and led to cracking in regions with mismatched deformation capacity.

Investigation into the effect of energy density on densification, surface roughness and loss of alloying elements of 7075 aluminium alloy processed by laser powder bed fusion

Gan Li et al.

Summary: The study found that optimizing processing parameters can achieve higher relative density, but cannot fully eliminate the problem of hot cracks. Surface quality issues are related to severe balling phenomenon and large gaps between tracks. In terms of low-melting-point elements content, there is a linear relationship between VED and the loss of zinc and magnesium, but no influence on the loss of copper and chromium.

Enhancing yield stress and uniform elongation in an ultrathin packaging steel via controlling dislocation density

Y. Z. Li et al.

Summary: This study demonstrates a method to achieve high strength and large uniform elongation of ultrathin sheet steels at low costs by simply using standard industrial procedures. An optimized double reduction process, which controls dislocation density and exploits the beneficial effects of bake hardening, was designed to improve the uniform elongation of ultrathin sheets without sacrificing yield stress. Precisely controlling dislocations plays an important role in producing low-cost ultrathin sheet steels with high strength and uniform tensile ductility, which are highly demanded for large-scale industrial production.

Han Chen et al.

Summary: The study investigated the effects of precipitation on ductility in precipitation hardening aluminium alloys.
