Ultrafine gamma-Fe(C), alpha-Fe(C) and Fe3C particles were prepared by arc-discharge synthesis in a methane atmosphere. The phases, morphology, structure and surface layer of the particles were studied by means of X-ray diffraction (XRD), transmission electron microscopy (TEM) techniques and ...
The EGS3 Monte-Carlo electron-photon transport simulation package has been used to calculate dose equivalent per unit fluence vs depth curves for broad parallel beams of mono-energetic electrons, positrons and photons incident on a 30-cm... Rogers,WO D. - 《Health Physics》 被引量: 230发表...
It was found that single Fe3C phase was obtained from the pre-reduced powders containing 3.26 and 0.59 wt.% oxygen for carburization periods of 15 and 30 min. The kinetic data for the carburization under pure CH4 indicates that there are essentially two successive distinct regimes: reduction of...
PRODUCTION OF NON-AGING HOT ROLLED STEEL PLATE WITH HIGH AVERAGE GAMMA-VALUEPURPOSE: To produce a hot rolled steel plate having high average γ-value as a substitute for that of cold rolled steel sheet, also having stable non-aging characteristic, and excellent in characteristics at a low cost...
