熱頑磁 的英文怎麼說
中文拼音 [rèwáncí]
熱頑磁
英文
thermoremanence-
It is a dozen metals in one ; now almost diamond - hard - - and again almost as soft as copper ; here brittle as glass ? there malleable1o as silver ; now welding quite readily - - again, very difficult to weld ; melting rather easily - - at other times difficult to diffuse ; usually very magnetic - - and : again almost non - magnetic ; an excellent conductor of heat and electricity - - and at times stubbornly resistant to both
鐵將十多種金屬特性合而為一：時而幾乎堅硬如金剛石，時而又柔軟如銅；此處易碎如玻璃，彼處又可展延如銀；時而很容易焊接，時而又很難焊合；有時相當易熔，有時又極難擴散；通常情況下富有磁性，但有時又幾乎磁性全無；本是熱和電的優良導體，但有時卻頑強地抗拒二者。The results showed that the microstructure of as - deposited tbdyfe ii 1ms were amorphous and the crystal of tbfe2 were found in films after annealing at 500. annealing films in vaccum could improve the saturation magnetization ms and the susceptibility, decrease the coercivity and the saturaion field, and make the direction of the magnetic moments parallel to the film plane
結果表明，制備態薄膜為非晶態結構，經過500真空退火熱處理后，薄膜出現了tbfe _ 2的結晶物，薄膜的矯頑力和外場的飽和磁場大大降低，飽和磁化強度增強，初始磁化率提高，易磁化軸轉向膜面。X - ray diffraction results revealed that the structure of as - deposited smco film was amorphous and crystallization happened after the films annealed at 500 in vacuum. the magnetic tests of smco thin films showed that its coercivity reduced with the increase of film ' s thickness while the ratio of mr / ms was opposite. the films " coercivity and mr / ms declined after it annealed at 500 because the machanism of magnetization were changed from domain wall nailing into magnetic nuclear forming
研究結果表明，由於雜質fe的摻入降低了smco薄膜的磁性能；制備態smco薄膜為非晶態結構，矯頑力hc隨著薄膜厚度的增加而減小，剩磁比mr ms隨膜厚增加而增加；經過500真空退火熱處理后，薄膜出現smcos的結晶物，矯頑力hc降低， mr ms減小，磁化機制由疇壁釘扎類模型轉為形核類模型。Ii. hc and mr / ms rise with the extension of time, which also because the fcc texture changes into fct texture
（二）隨著熱處理時間的延長，矯頑力和剩磁比顯示出與（ l ）相同的變化趨勢，其解釋也是同樣的。The formation process of w - type ferrite underwent from oxide of metal, the m - type transition phase to final w - phase. when the heating rate was 5 / min, at 900 for 3 hrs and 1200 for 4 hrs, pure m - type and w - type ferrites were formed in air respectively. with heat treatment temperature increasing, crystal structure was more intact, the saturation magnetization increased and the coercive force decreased
熱處理過程表明， m型鐵氧體直接由金屬氧化物反應形成，未經歷尖晶石中間相； w型鐵氧體形成由金屬氧化物到m相過渡相最終向w相的轉變；當升溫速率為5 min ，溫度在900 ，保溫3小時和1200保溫4小時，就分別形成單相m相和w相鐵氧體；隨著熱處理溫度的升高和保溫時間的延長，衍射峰變尖銳，結晶更完整，空心微球的飽和磁化強度增大，矯頑力減小。It has been found that a preferable orientation can be obtained while both the smco5 phase and the sm2co17 phase have deposited plenty in the two - steps heat treatment
而合適的兩級退火熱處理能使smco5和sm2co17永磁相充分析出，並形成一定的擇優取向，從而可以顯著提高薄膜的矯頑力。Analyses showed that the effect of heat treatment is remarkable to 304 stainless steel fibers. and a new martensitic phases formed, and ms increased during annealing at 180c ; annealing above 180c decreased the ms. after annealed in the range of 380c ~ 440 c, the he increased and the product ( mr hc ) improved. it was also shown that annealing affected the mechanical properties of 316l ss fibers obviously
304不銹鋼纖維在180附近退火處理其ms略增加，其內部相變與一般的304不銹鋼體材料存在差別； 380 440區間退火處理，其矯頑力急劇增加、磁能積參數配合比較好；退火熱處理對316l不銹鋼纖維的力學性能作用明顯。分享友人
