Surface nanocrystallization (SNC) modification can be used to realize the high-efficiency derusting of rusted Cr-alloyed rebar and obtain nanostructured grains on surface rebar. The corrosion resistance performance SNC in a simulated Cl--containing concrete pore solution was evaluated basis electrochemical experiments. Potentiodynamic polarization testing showed that passivation current density...

The aim of the present study was to make a fenofibrate (FNB) nanocrystal (NC) by wet media milling, characterizations and formulates into oral strip-films (OSFs). Mechanical properties, redispersion study, and solid-state characterizations results suggested that reduction of drug crystal size at nanoscale and incorporation into OSFs does not affect the solid-state properties of the drug. In vit...

The microstructure evolution of Zr-1.1Nb-1.51Fe-0.26Cu-0.72Ni zirconium alloy, irradiated by 800 keV Kr2+ ions at 585 K using the IVEM-Tandem Facility at Argonne National Laboratory, was observed by in situ transmission electron microscopy. A number of β-Nb precipitates with a body-centered cubic (BCC) structure were distributed in the as-received zirconium alloy with micrometer-size grains. Kr...

An evident inequality between the enthalpy of crystallization of amorphous selenium, DHx , and the enthalpy difference between the undercooled liquid and the conventional polycrystalline selenium, DHl→c, was observed, which is inconsistent with the widely accepted idea that the two enthalpies should be equal. The inequality between the two enthalpies is attributed to the excess enthalpy of the ...

FeCo-based ferromagnetic alloys (HITPERM variants) of composition Fe44 5Co44 5Zr7B4, Fe44Co44Zr5 7B3 3Ta2Cu1, Fe44Co44Zr5 7B3 3Mo2Cu1, and Fe37 2Co30 8Zr7B4Cu1 were prepared by melt-spinning amorphous precursors, followed by nanocrystallization. Samples were characterized using vibrating sample magnetometry (VSM), x-ray diffraction (XRD), and differential scanning calorimetry (DSC). VSM was use...

In the thermochemical process of low-carbon steel nitridation, improvements of mechanical properties are governed by the nature (hardness, thickness, etc.) of the compound layer since the compound layer will be kept under working conditions. Because of low nitrogen diffusivity in steel and low mass transfer between gaseous reaction and steel, long duration and high temperature are classically u...
