【摘要】 本文研究了掺杂３ａｔ％Ｃｕ对Ｎｄ（Ｆｅ，Ｔｉ）１２化合物结构与磁性的影响。结果表明，加入３ａｔ％Ｃｕ后，ＴｈＭｎ１２结构相的形成温度由９００℃降至７５０℃，但也对渗氮造成困难。预先将样品在３００℃氢气中进行活化处理，有利于形成氮化物。氮化物的内禀矫顽力随退火温度的升高而增大，到８５０℃达最大值。更多还原

【Abstract】 The effects of the 3at % Cu addition on the structure and magnetic properties of Nd（Fe,Ti）₁2 have been studiedIt shows that,with adding 3at % Cu,the temperature for forming 1:12 phase decreases from 900℃ to 750℃,and the addition of Cu makes nitrogenation difficultThe activation pretreatment of specimen in hydrogen at 300 ℃ is favorable to the formation of the nitrideWith increasing the annealing temperature,the nitride’s intrinsic coercivity increases and culminates at 850℃.更多还原
