High-temperature magnetic properties of mechanically alloyed SmCo 5 and YCo5 magnets
The high-temperature coercivity of mechanically alloyed and subsequently annealed RCo5 (R= Sm and Y) is studied. The annealed materials have the hexagonal CaCu5 structure with 2 : 17 (or 1 : 7) regions as a minor phase. High-temperature magnetic measurements show that the coercivities of materials decrease with increasing temperature from room-temperature to 873 K, but that the temperature coef...
متن کاملthe effect of explicit instruction of metacognitive strategies on reading comprehension among iranian high school students
the present study seeks to determine the effect of explicit instruction of metacognitive strategies on iranian high school students’ reading comprehension ability. it also attempts to investigate the relationship between the learners reading comprehension and metacognitive strategies. furthermore, the study investigates whether iranian efl female high school students are high, medium, or low me...
Exchange-coupled nanoscale SmCo/NdFeB hybrid magnets
Nanoscale hybrid magnets containing SmCo5 and Nd2Fe14B hard magnetic phases have been produced via a novel ‘‘in-one-pot’’ processing route. The grain size of the processed bulk composite materials is controlled below 20 nm. The refinement of the nanoscale morphology leads to effective inter-phase exchange coupling that results in single-phase like magnetic properties. Energy product of 14 MGOe ...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولEffect of Fe, Cu, Zr, and Ti on the Magnetic Properties of SmCo-1 : 7 Magnets - Magnetics, IEEE Transactions on
The effect of Fe, Cu, Zr, and Ti substitution on magnetic properties of SmCo 1 : 7 magnets at temperatures up to 500 C were studied. As-milled amorphous Sm(Co,Fe,Cu,Ti–Zr)7 magnets crystallized in the TbCu7-type structure after annealing at 750 C for 2 h. A room-temperature intrinsic coercivity of around 2.5 T is obtained for compositions SmCo6 4Zr0 2Ti0 4 and SmCo6 4Fe0 1Zr0 1Ti0 4. The high c...
