Microwave embrittlement

چکیده
Mikrovlnné žiarenie frekvencie 2,45 GHz bolo použité na vzorkách uhlia z rôznych anglických lokalit, na ich tepelnú predúpravu pred rozpojovaním. Získané údaje poukazujú na vplyv mikrovlnnej tepelnej úpravy na relatívnu meliteľnosť uhlia. Výrazná redukcia ( 20 –40 % ) relatívnej energie mletia bola zaznamenaná už po pomerne krátkom čase pôsobenia mikrovlnného žiarenia (3 –8 min). Vplyv mikrovlnnej predúpravy na fyzikálnu a chemickú štruktúru uhlia, ako aj na odsírenie uhlia, bol tiež analyzovaný.

Investigation of microwave-assisted concrete recycling using single-particle testing
Microwave heating stands as a strong candidate for selective liberation of multiphase materials like concrete. It takes advantage of the differences in thermal, dielectric and mechanical properties of each of the components to create stress gradients that can lead to grain boundary fracture and embrittlement. The work and results reported are concerned with selective liberation of concrete’s ra...
متن کاملEffects of tungsten on the hydrogen embrittlement behaviour of microalloyed steels
The effects of tungsten (W) additions (0, 0.1, 0.5 and 1 wt.%) on the hydrogen embrittlement behaviour of microalloyed steels were systematically investigated by means of slow strain rate tests on circumferentially notched cylindrical specimens, and the mechanism of hydrogen-induced embrittlement was discussed. W addition is found to increase the activation energy of hydrogen desorption. Micros...
متن کاملStudies of Radiation Embrittlement of Model Alloys by Thermoelectric Measurements and Positron Annihilation Spectroscopy
One of the basic mechanisms of radiation embrittlement of steels and welds is due to matrix damage. Embrittlement results in a raise in the ductile-to-brittle transition temperature, which is normally used as indicator of the degradation status of the material. Other methods different than mechanical tests can be used to follow embrittlement like small punch test, non-destructive measurements o...
متن کاملA Simple Evaluation of Grain Boundary Diffusion in Liquid Metal Embrittlement
Most works on liquid metal embrittlement up to 1960 are compiled by Rostoker et al. (1) They stated that grain boundary diffusion is not an origin of embrittlement, since its rate, in general, is too small. However, Waterhouse et al. (2), performing the experiment on 70/30 brass wetted with mercury, suggested that dissolution of zinc from grain-boundaries into mercury accelerates the degree of ...
متن کاملRadiation Embrittlement Prediction Models and The Impact of Irradiation Temperature
A new methodology is developed for the prediction of RPV embrittlement that utilizes a combination of domain models and nonlinear estimators including neural networks and nearest neighbor regressions. The Power Reactor Embrittlement Database is used in this study. The results from newly developed nearest neighbor projective fuser indicate that the combined embrittlement predictor achieved about...
