Optimization of annealing modes of cast tool made of R6M5L steel [PDF]

Металознавство та обробка металів, 2019
A simple configuration cast tool made by the technology of chill casting with intensive cooling during crystallization from R6M5L steel is characterized by a fine-grained structure, increased alloying of the solid solution and a hardness of 62-63 HRC; it

Role of disordered bipolar complexions on the sulfur embrittlement of nickel general grain boundaries [PDF]

, 2018
Minor impurities can cause catastrophic fracture of normally ductile metals. Here, a classic example is represented by the sulfur embrittlement of nickel, whose atomic-level mechanism has puzzled researchers for nearly a century.

Intrinsically Disordered Protein‐Inspired Nanovector‐Based Coacervates for the Direct Cytosolic Transport of Biomacromolecules

Advanced Materials, EarlyView.
Intrinsically disordered protein‐inspired nanovectors (IDP‐NVs) form stable nanocoacervates (NCs) with diverse biomacromolecules. In situ conformational changes confer stability and adaptability to NCs under dynamically changing physiological conditions.

Dielectric and polarization experiments in high loss dielectrics: a word of caution [PDF]

, 2008
The recent quest for improved functional materials like high permittivity dielectrics and/or multiferroics has triggered an intense wave of research. Many materials have been checked for their dielectric permittivity or their polarization state.

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.

In situ measurements of density fluctuations and compressibility in silica glass as a function of temperature and thermal history

, 2005
In this paper, small-angle X-ray scattering measurements are used to determine the different compressibility contributions, as well as the isothermal compressibility, in thermal equilibrium in silica glasses having different thermal histories.

Evolution of Microstructure and Texture during Isothermal Annealing of a Heavily Warm-rolled Duplex Steel

, 2014
The evolution of microstructure and texture during isothermal annealing of a heavily warm-rolled duplex steel (DSS) was studied. For this purpose a DSS steel was hot rolled, homogenized at 1 448 K and subsequently warm-rolled to 90% reduction in ...

Porous Iridium Oxide Inverse Opal Catalysts Enable Efficient PEM Water Electrolysis

Advanced Materials, EarlyView.
Porous iridium‐based inverse opal (IrOx‐IO) structures are introduced as high‐performance, unsupported PEM‐WE anode catalysts. Their electrochemical behavior is analyzed through porosity/surface area tuning, voltage breakdown, and circuit modeling.

Effects of cooling rate on isothermal spheroidizing annealing of hot-rolled GCr15 bearing steel

Journal of Materials Research and Technology
The effects of cooling rate on isothermal spheroidizing annealing (SA) of hot-rolled GCr15 bearing steel have been investigated. The results show that controlling the cooling rate between austenitizing and secondary annealing within a specific range is ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,
