Quenching and Partitioning (Q&P) technology

Book of abstracts of the 17th International symposium of the Croatian Metallurgical Society - SHMD 2024, Materials and metallurgy
The direction of finishing heat treatment, which is based on the principle of Quenching and Partitioning (Q&P), has been actively developing in recent years. Q&P technology (it can be considered a type of isothermal hardening) can be applied to a wide range of steels, including those with a wider range of carbon concentrations.

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Enhancing strength and ductility in ultrahigh-strength steel via flash-heated IQP with lamellar heterostructure and chemical heterogeneity

Materials & Design
To develop ultrahigh-strength steel with both excellent mechanical properties and cost efficiency, this study integrates complete austenitization (CA), intercritical quenching (IQ), and flash heating quenching and partitioning (FHP).

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

A Functional 2D Carbon Allotrope Combining Nanoporous Graphene and Biphenylene Segments

Advanced Materials, EarlyView.
The synthesis of a novel nanoporous graphene (NPG) is reported with biphenylene segments via thermal fusion of 12‐armchair porous graphene nanoribbons grown on gold surfaces. Characterization using STM, AFM, and DFT reveals low‐defect semiconducting behaviour and tunable band gaps.

Quenching and Partitioning of High-Aluminum Steels

, 2017
The quenching and partitioning response of aluminum-containing steels was investigated primarily through dilatometry and microstructural analysis through electron backscatter diffraction. It was found that 2-3 wt-% aluminum content raises the Ac3 temperature to levels that cannot be predicted by current thermodynamic models.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

Advanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses
