Relationship Between Micro‐Level Circular Economy and Sustainable Performance in the Metalworking Industry

Sustainable Development, EarlyView.
ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...

Prediction of Residual Stresses During the Hot Forging Process of Spherical Shells Based on Microstructural Evolution

Journal of Manufacturing and Materials Processing
A unified viscoplastic constitutive model based on internal physical variables was proposed to predict the viscoplastic mechanical behavior and microstructure evolution of metals during hot forging.

Exploiting Device Deformability for Fluid and Particle Manipulation

Small, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Forming strategy of CF/PPS V-shaped components using multi-point flexible molds: Relationship between process and quality

Journal of Materials Research and Technology
Thermoplastic composites are widely used in producing small-batch, customized aerospace components, yet their hot-stamping process still encounters challenges due to the complex fabrication and high cost of solid molds.

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).

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Effect of Microstructures on Yield Strength in Hot-Stamped Steel Sheet

MATEC Web of Conferences, 2015
For automotive structural parts, hot stamping is being increasingly used because of the need for both higher fuel efficiency and crashworthiness. The yield strength of hot-stamped steel sheet is lower than that of water-quenched steel sheet.
