Unraveling the origin of extra strengthening in gradient nanotwinned metals

Zhao Cheng et al.

Summary: This study investigates the extra strength of gradient nanotwinned (GNT) Cu compared to uniform nanotwin counterparts. The research finds that the extra strength of GNT Cu is mainly due to the extra back stress resulting from the nanotwin thickness gradient. The structural gradient in GNT Cu leads to an increasing plastic strain gradient, which raises the extra back stress. The combined experimental and modeling results reveal a fundamental connection between the gradient structure and extra strength in GNT Cu through the mechanistic linkages of plastic strain gradient, heterogeneous dislocation structure, microscale internal stress, and extra back stress.

Metallurgy, mechanistic models and machine learning in metal printing

T. DebRoy et al.

Summary: Metal printing is widely used in key industries to produce complex parts that are difficult to manufacture conventionally, with metallurgy, mechanistic models, and machine learning driving its continued growth. Additive manufacturing allows for the printing of metallic parts with specific chemical compositions and properties, but the selection of alloys, printing processes, and variables results in a diverse range of microstructures, properties, and defects that impact the serviceability of printed parts.

Hierarchical crack buffering triples ductility in eutectic herringbone high-entropy alloys

Peijian Shi et al.

Summary: The study demonstrates a directionally solidified eutectic high-entropy alloy with a hierarchically organized herringbone structure that reconciles crack tolerance and high elongation. The self-buffering herringbone material achieves an ultrahigh uniform tensile elongation while maintaining strength.

Spinodal-modulated solid solution delivers a strong and ductile refractory high-entropy alloy

Zibing An et al.

Summary: A new strategy is demonstrated to achieve ductile BCC HfNbTiV by decomposing the BCC arrangement into two different phases via spinodal decomposition, resulting in chemical composition modulations and elastic strain on a length scale of a few tens of nanometers. The periodically spaced beta* with large lattice distortion is particularly effective in hindering dislocation movement, leading to strain hardening and enhancing plastic strain delocalization, ultimately achieving high yield strength and tensile strain to failure.
