Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures
Small, EarlyView.Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Effect of post-weld heat treatment on AA6351 friction stir welds
Abstract Al-Mg-Si (6xxx) alloys have superior properties to other aluminium alloys, making them suitable for aerospace and defence applications. However, their weldments are susceptible to various issues that affect their microstructural changes, mechanical properties, and corrosion resistance.

Smart Molecules, EarlyView.This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.

POST WELD HEAT TREATMENT OF A HIGH-TEMPERATURE STEEL [PDF]
, 2019 After welding, heat treatment of weld joints on components made of high-temperature steels is usually necessary. In this work, several microstructures occurring in the heat affected zone (HAZ) in X10CrMoVNb9-1 hightemperature steel were simulated: Coarse grained HAZ (CGHAZ), two different fine grained HAZ (FGHAZ) and intercritical HAZ (ICHAZ).

steel research international, EarlyView.Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

steel research international, EarlyView.Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

steel research international, EarlyView.Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...
