Effect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets
Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...
متن کاملModification of the Interface Nanostructure and Magnetic Properties in Nd-Fe-B Thin Films
The effects of Nd2Fe14B grain size and Nd coating on the coercivity in sputter-deposited Nd-Fe-B/Nd thin films have been investigated in order to gain an insight into the coercivity mechanism of Nd-Fe-B magnets. Highly textured Nd2Fe14B particles were grown successfully on the MgO(100) single-crystal substrate with the Mo underlayer. As the Nd-Fe-B layer thickness t NFB was decreased from 70 to...
متن کاملStructure and thermal stability of Fe : Al2O3 nanocomposite films
Nanocomposite films consisting of Fe nanocrystals (NCs) embedded in an amorphous Al2O3 matrix have been fabricated by alternate pulsed laser deposition in vacuum. The size, shape and distribution of the Fe NCs have been analysed by high resolution electron microscopy. The thermal stability of the films has been studied by in situ annealing in the electron microscope, and the chemical state of t...

15 صفحه اولthe effect of consciousness raising (c-r) on the reduction of translational errors: a case study
در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
