Influence of Si Content and Milling Duration on the Microstructure and Mechanical–Tribological Properties of AlCoCrFeNiSi High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
Si‐doped AlCoCrFeNi high‐entropy alloys are synthesized by mechanical alloying to reveal the effect of Si content and milling time on phase evolution, microstructural refinement, and tribological behavior. A transition from FCC to BCC structure, significant grain refinement, and enhanced hardness and wear resistance are achieved, with the 4 at% Si ...

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Nanotwins induced the formation of passive films and protective oxides: an effective pathway to enhance corrosion resistance in ultra-high strength-ductility nanolayered dual-phase steel

open access: yesJournal of Materials Research and Technology
This study focuses on introducing twin structures into the nanolayered structure and deeply explores its influence on the initial corrosion behavior and product evolution of martensite-austenite dual-phase high-strength steel, with emphasis on the role ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Numerical simulation on the microstress and microstrain of low Si-Mn-Nb dual-phase steel

open access: yes, 2010
According to the stress-strain curves of single-phase martensite and single-phase ferrite steels, whose compositions are similar to those of martensite and ferrite in low Si-Mn-Nb dual-phase steel, the stress-strain curve of the low Si-Mn-Nb dual-phase ...
