Highly integrated, alignment healing, and full‐recyclable multifunctional flexible devices based on dynamic covalent bonds

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.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

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

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).

Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

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 ...

Synergistic effect of solution-aging on phase evolution and high-temperature creep resistance in inertia-friction-welded Ti–6Al–4V aerospace components

Journal of Materials Research and Technology
This study investigates the effects of a post-welding T6 heat-treatment strategy, namely solid solution and ageing treatment, on the microstructural evolution and high-temperature mechanical properties of Ti–6Al–4V (TC4) alloy joints produced by inertia ...

Effect of Heat Treatment on Post Weld Railway Track

FUDMA Journal of Engineering and Technology
The structural integrity of railway tracks is critically influenced by welding processes and subsequent treatments. This study investigates the effects of various post-weld heat treatment methods; annealing, normalizing, and tempering on the mechanical and microstructural properties of welded high-carbon steel railway tracks.

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

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 ...

Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...
