Kinetic and Metallography Study of the Oxidation at 1250 °C of {Co+Ni}-Based Superalloys Containing Ti to Form MC Carbides

open access: yesMetals, 2021
Six conventionally cast chromium-rich titanium-containing alloys based on cobalt and nickel with various Co/Ni ratios were considered. They were tested in oxidation in air at 1250 °C for 70 h in a thermo-balance.

Note on the Isothermals of Ethyl Oxide [PDF]

open access: yesProceedings of the Royal Society of Edinburgh, 1892
The first three pressure-columns of the following little table were constructed from the elaborate data given by Drs Ramsay and Young in their important paper “On Evaporation and Dissociation,” Part IV. (Phil. Mag., May 1887). They give, in metres of mercury, the pressures required to confine one gramme of oxide of ethyl to various specified numbers of

High-Temperature Oxidation and Microstructural Changes of Al0.75CoCrFeNi High-Entropy Alloy at 900 and 1100 °C

open access: yesMetals, 2023
The development of high-entropy alloys (HEAs) for high-temperature applications has been driven by the limitation of nickel-based superalloys in achieving optimal efficiency at higher temperatures for higher efficiency in power generation engines.

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

open access: yes, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

Isothermal oxidation of Inconel 625 superalloy at 800 and 1000 °C: Microstructure and oxide layer characterization

open access: yes, 2020
Superalloys are widely used in applications at high temperatures and severe environments. Inconel 625 is one of the most applied superalloys due to its high oxidation resistance and mechanical properties, however studies in air lab and temperatures not ...

Kinetic Modeling of Isothermal or Non-isothermal Adsorption in a Pellet: Application to Adsorption Heat Pumps [PDF]

open access: yes, 2010
Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption process. Because the heat effects associated with adsorption are comparatively large, the assumption of isothermal behavior is a ...

Thermal oxidation kinetics of additive free polyamide 6-6 [PDF]

open access: yes, 2013
Thermal aging of an additive free PA 6-6 has been elucidated at 90, 100, 120, 140, 150 and 160 C in airventiled ovens by Fourier transform infrared spectrophotometry, viscosimetry in molten state and uniaxial tensile testing.

First report on cold-sprayed AlCoCrFeNi high-entropy alloy and its isothermal oxidation

open access: yesJournal of Materials Research, 2019
Cold-sprayed high-entropy alloy (HEA) coatings have been generated for the first time. Mechanically alloyed (MA) AlCoCrFeNi powder was chosen as feedstock, owing to the extensive literature on this alloy.

ISOTHERMAL OXIDATION OF TIN FILMS

open access: yesActa Physica Sinica, 2000
The growth kinetics of the oxide film and oxidation mechanism on tin films prepared by the electron-beam evaporation in the temperature range of 250—400℃ by an isothermal process were investigated. Based on an X-ray diffraction, auger electron spectrum, scanning electron microscope and alpha-step instrument, the evolution of the structure, composition,
