The microstructure and the relationship between the coercivity and the structure of the ball milled Nd_(14)Dy_1Fe_(72)Co_5B_8 alloy were investigated.It is suggested that the coercivity of the milled alloy results from domains wall pinning at boundaries.At the initial state of milling,the coercivity increases with milling time,which may mainly be attributed by the increa- se of boundary density caused by decreasing grain size.At the sage of more than 30 hrsof milling,the coercivity decreases with milling time;this eff- ect may be due to an introduction of mierostrains and defeets into the crys- tal lattice in the process of mechanical grinding,which would eventually reduce the anisotropy field of the 2-14-1 phase.

本文采用 X 射线衍射,透射电镜和振动样品磁强计等技术研究了 Nd_(14)Dy_1Fe_(72)Co_5B_8合金在高能球磨过程中的结构变化以及结构与矫顽力的关系。我们认为高能球磨 Nd_(14)Dy_1Fe_(72)Co_5B_8合金的矫顽力源于晶界对畴壁的钉扎。在球磨初期,矫顽力随球磨时间的增加而增加,这主要归结于晶粒细化引起的晶界密度的增加。当球磨时间超过30小时,矫顽力随球磨时间的增加而减小,这可能是由于在球磨过程中引入很大的微观应力和高密度的缺陷,导致 R_2TM_(14)B(R=Nd、Dy;TM=Fe、Co)磁性相的磁晶各向异性场降低。

New materials processing technique called mechanical alloying(MA)has attracted general attention in recent years. To date, it appears that almost all the research effect of MA has focussed on metallic system. The structure variation process of the ZrO2-30mol% CeO2 mired ceramic powder has been studied in the present paper. It has been found for the first time that MA of ceramics is also possible.

The Al-rich metastable NiAl phase obtained by high-energy milling can transfer to rnetastable Ni2Al3 phase through heat treatrnent,Its M6ssba-uer spectra show that the state and distribution of elements and electon structure of the alloy were obviously affected during milling. Experiments indicated that solid state reaction took place in the alloying process.The phase formed in high-energy milling and subsequent annealing was the same as in a fully peritectic reaction.

利用高能球磨机对Ni-Al-Cr-Fe合金进行球磨,得到亚稳的NiAl相,再经适当的热处理可以得到主相为NiAl3的亚稳相。Mossbauer谱结果表明:高能球磨明显改变了添加元素的分布状态及合金原子的电子结构,并且可使合金元素分布均匀。实验表明高能球磨过程中发生了固相反应,反应产物在适当的退火条件下可以得到和充分包晶反应相同的相结构。
