Advanced Engineering Materials, EarlyView.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning
Advanced Engineering Materials, EarlyView.The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

Ductile B2 Intermetallics-Driven Strength-Ductility Synergy in Heterolaminated Multi-Principal Element Alloys. [PDF]
Adv Sci (Weinh)Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

Advanced Engineering Materials, EarlyView.HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Growth-state-dependent deformation stability of discontinuous precipitation in Cu–Ni–Si alloys
Journal of Materials Research and TechnologyDiscontinuous precipitation (DP) in Cu–Ni–Si alloys can either promote strengthening or diminish it through fragmentation, yet the factor governing these contrasting effects remains unclear.

Geometrically nonlinear analysis of thin-walled composite box beams [PDF]
, 2009 A general geometrically nonlinear model for thin-walled composite space beams with arbitrary lay-ups under various types of loadings has been presented by using variational formulation based on the classical lamination theory.

Advanced Engineering Materials, EarlyView.This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...
