Studies were made of the mechanical alloying of an oxide dispersion strengthened majority γ'-phase Ni-base superalloy by analyses of SEM and X-rays. By a high energy ball milling technique, a mechanical solid-solution may be formed and the mechanical alloying may be realized from various raw metal powders, The CrNi-based masteralloy and elements such as W, Mo, Ta, etc. in the raw metal powders were continually solid-soluble into Ni matrix and the lattice parameter of Ni-base solid-solution was increased with processing time. Simultaneously, nearly random dispersion of the ultraflne oxide particles was obtained in the metal matrix. Although the micro-area compositions of the mechanical solid-solution is segregated, yet it may be improved by certain effective steps. The technical parameters of the mechanical alloying in aUoy studied were also analyzed and discussed.

本文用扫描电镜和X射线对一种复杂的弥散强化Ni基高温合金的机械合金化进行了研究。实验表明,采用高能球磨的方法可以使原料中的各种金属粉末间形成机械固溶体,实现合金化。在球磨过程中,原料中的Cr-Ni基母合金以及W,Mo,Ta等元素不断向Ni基体中周溶,使Ni基固溶体γ_(Ni)的点阵参数逐渐增大。同时,超细氧化物粒子在基体中也逐步达到理想的分布状态。这种机械固溶体虽存在一定的微区成分偏离,但可以通过某些有效措施使之显著减小。本文对机械合金化工艺参数也进行了分析和讨论。

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...

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。

The structure and microstructure of Cu-Fe powder mixture with different com-position during different milling time were analyzed by X-ray diffraction and electrondiffraction。The results show that under the conditon of high energy milling,the solid statesolubility of both Cu in Fe and Fe in Cu are enhanced substantially,and the structure of fcccan be extended to 60 at.-% Fe.

采用 X 射线衍射,电子衍射等方法,对不同成分的 Fe-Cu 二元混合物粉末经不同研磨时间的结构进行了测定、分析。结果表明,在高能球磨条件下,原本在固态下溶解度极低的 Fe-Cu 系列的溶解度大为提高,其面心立方结构一直可维持到60at.-%Fe。
