A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Metal-matrix composite fabricated with gas tungsten arc melt injection and precoated with NiCrBSi alloy to increase the volume fraction of WC particles

open access: yesScience and Engineering of Composite Materials, 2017
The volume fraction, dissolution, and segregation of WC particles in metal-matrix composites (MMCs) are critical to their wear resistance. Low carbon steel substrates were precoated with NiCrBSi coatings and processed with gas tungsten arc melt injection

Study of the wear resistance of Hypereutectic Fe–Cr–C Hardfacing Alloy reinforced with carbide particles

open access: yesMaterials Research Express, 2022
The microstructures and wear resistance of hypereutectic Fe–Cr–C hardfacing alloys reinforced with carbide particles was studied. The results showed that when the sizes of the M _7 C _3 carbides were small, the wear resistance of the hardfacing alloy was

The Relation Between Ultimate Tensile Strength and Carbide Size in Steel

open access: yes, 1976
The paper demonstrates that a definite and simple relationship exists between ultimate tensile strength (or Brinell hardness) and the carbide size in steels, for a given carbide shape and volume fraction.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Effects of Size and Volume Fraction of Carbide Particles on Strength and Fracture Toughness of P/M High Speed Steel.

open access: yesJournal of the Society of Materials Science, Japan, 1992
Fracture toughness tests of P/M high speed steels with different carbide sizes were carried out by using three point bend specimens with fatigue precrack. Tensile and bending strength tests were also carried out. The heat treatment to control the size of carbide particle also resulted in the change of volume fraction of carbide particles: the volume ...

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

open access: yesAdvanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

open access: yesAdvanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...
