Hot deformation characteristics and kinetics analysis for Ni‐based corrosion resistant alloy

open access: yesEngineering Reports, 2021
The hot deformation characteristics of Nickel‐based corrosion resistant alloy was studied in the temperature range of 1050°C to 1200°C and the strain rate range of 0.001 to 0.1 second−1 by employing hot compression tests.

C crystal growth via CVD [PDF]

open access: yes, 2023
We investigated the growth mechanism of 2D Mo2C crystals by chemical vapor deposition (CVD) under various time and temperature conditions. The growth kinetics and mechanism of Mo2C on Cu via chemical vapor deposition (CVD) were investigated using a ...

Isothermal Melt Crystallization Kinetics of PP/organoclay Blends

open access: yesMATEC Web of Conferences, 2016
Polystyrene (PP)/organoclay (OMMT) blends were prepared by co-rotating twin-screw extruder. The effects of OMMT on isothermal crystallization behaviors of blends was studied by differential scanning calorimetry (DSC).

Crystallization kinetics of K2O·TiO2·3GeO2 glass studied by DTA [PDF]

open access: yesScience of Sintering, 2008
Crystallization kinetics of K2O·TiO2·3GeO2 glass was investigated by differential thermal analysis (DTA). Experiments were performed on powder samples with a particle size < 0.037 mm. The glass samples were heated at different rates in the temperature

A kinetic analysis of the melting HA/Y-PSZ/HDPE nano bio composite for hard tissue materials

open access: yesJournal of King Saud University: Engineering Sciences, 2018
Melting characteristics of high-density polyethylene (HDPE) mixed with nano-size ceramic fillers (hydroxyl apatite and yttria stabilised zirconia) was analysed using the isochronal heating rate between 10 °C min−1 and 80 °C min−1.

Johnson-Mehl-Avrami-Kolmogorov equation for prediction of compressive strength evolution of geopolymer

open access: yes, 2015
Geopolymers are cement-free constructional materials and for their production much lower greenhouse gases are emitted than traditional concrete. In this study, compressive strength of geopolymers was related to their degree of geopolymeric reactions ...

Surface Diffusion-Controlled Jonhson–Mehl–Avrami–Kolmogorov Model for Hydrogenation of Mg-based Alloys

open access: yes, 2023
The use of the Jonhson–Mehl–Avrami–Kolomogorov (JMAK) model has become prevalent in the kinetic analysis for Mg-based hydrogen storage alloys. However, the classical JMAK model has shown inadequate results in certain cases, resulting in poor fitness and ...

Kolmogorov-Johnson-Mehl-Avrami model fitted to early COVID-19 mainland China infection outbreak data [PDF]

open access: yes
In 2007 Avramov provided theoretical framework which suggests that the Kolmogorov-Johnson-Mehl-Avrami (KJMA) model, which is commonly used in materials science to describe transformation phenomena, could be used in describing infection spreading in human

Metastable Austenite Transformation Kinetics of Medium-Carbon Silicon-Rich Steel during Partitioning in a Q & P Process

open access: yesMetals, 2020
In the present study, quenching and partitioning (Q & P) treatment of a medium-carbon silicon-rich steel was processed by a dilatometer. The volume fraction of the retained austenite at different partitioning times was determined by X-ray diffraction ...
