    在成核介导的磁化反转过程中直接观察单个巴克豪森雪崩
    摘要:
    我们报告了巴克豪森雪崩的缩放行为 [H. 巴克豪森,Z. Phys。20, 401 (1919).] 沿着 CoCrPt 合金膜的磁滞回线,对于 200 Oe 的每个场步具有垂直磁各向异性。通过空间分辨率为 15 nm 的软 X 射线显微镜直接观察单个巴克豪森雪崩。巴克豪森雪崩表现出幂律缩放行为,其中随着外加场接近 CoCrPt 膜的矫顽力,幂律分布的缩放指数从 1±0.04 急剧变化到 1.47±0.03。我们推断这是由于相邻域的耦合。

  • The influence of chromium on the defect structure and their mobility in nonstoichiometric cobaltous oxide
    作者:S Mrowec、Z Grzesik

    日期:2003.8
    the mobility of point defects in pure metal deficient cobalt oxide (Co 1− y O) and in Co 1− y O–Cr 2 O 3 solid solutions have been studied as a function of temperature (1223–1573 K) and oxygen pressure (10–10 5 Pa) using microthermogravimetric techniques. It has been shown that the predominant defects in pure and Cr-doped cobaltous oxide are singly ionized cation vacancies, and 3% at of dopant is high
    摘要 研究了纯金属缺钴氧化物 (Co 1− y O) 和 Co 1− y O–Cr 2 O 3 固溶体中的缺陷结构和点缺陷迁移率与温度 (1223–1573 K) 的关系和氧气压力 (10–10 5 Pa) 使用微热重技术。已经表明,纯的和掺杂 Cr 的氧化钴中的主要缺陷是单电离的阳离子空位,3% at 的掺杂剂足够高,可以将这种固溶体中主要缺陷的浓度固定在一个恒定水平,远高于在纯 Co 1− y O 中。再平衡速率测量表明,纯 Co 1− y O 中的化学扩散系数和点缺陷的迁移率与浓度无关,强烈暗示尽管它们的浓度相当高,但预计不会出现相互作用和缺陷聚集。另一方面,在 Cr 掺杂的氧化钴中,再平衡率测量表明,在这种情况下,缺陷结构更加复杂,尽管单电离的阳离子空位似乎仍然是主要缺陷。
  • The anisotropic first-neighbour contribution to the hyperfine field in hexagonal-close-packed Co: a nuclear magnetic resonance study of diluted alloys and multilayers

From the results on Co/Cr and Co/Ru multilayers it is deduced that the impurity neighbours out of the c-plane depress the Co hyperfine field less than the in-plane impurity neighbours. Comparison with the alloys CoCr and CoRu suggests a similar conclusion for CoMn alloys. As to CoCu systems, the situation is the opposite, although there
    核磁共振已在杂质浓度低于 1 at.% 的 CoCr、CoRu、CoMn 和 CoCu 六方合金以及存在于相应 Co/M 多层界面的二维合金中进行了研究,其中 Co 采用 hcp 结构。所有研究的合金都观测到两颗低频卫星,而立方合金只观测到一颗。它们的起源与 Co 的第一个配位壳中存在两个不等价的位点有关,因为 hcp Co 偏离了理想的紧凑结构。从 Co/Cr 和 Co/Ru 多层膜的结果可以推断,c 面外的杂质邻居比面内杂质邻居对 Co 超精细场的抑制要小。与合金 CoCr 和 CoRu 的比较表明 CoMn 合金的类似结论。对于 CoCu 系统,情况正好相反,

    Abstract Enthalpies of formation of 12 alloys from (cobalt + chromium) have been measured by solution calorimetry at 473 K and found to be quite large and positive, suggesting a high misfit-energy, with implications regarding the formation of a σ-phase in this system. The compositional dependence of the measured values is observed to accord with the phase-field boundaries of Hansen and Anderko(1) at

  • Microstructure and dry sliding wear behavior of ultrafine-grained Co-30 at% Cr alloy at room and elevated temperatures
    作者:Cancan Zhao、Jian Zhou、Qingsong Mei、Fuzeng Ren
    DOI:10.1016/j.jallcom.2018.08.092
    日期:2019.1
    Co-Cr-based alloys have been widely used as mechanical components where high wear-resistance is required. However, conventional Co-Cr alloys usually have coarse-grained microstructures with phase coexistence of both hexagonal close packed (hcp) epsilon-Co and face-centered cubic (fcc) gamma-Co. The wear resistance of the Co-Cr alloys could be further enhanced by grain refinement and exclusion of gamma-phase. Here, a Co-30Cr (at%) bulk alloy consisting of ultrafine-grained matrix of epsilon-phase and uniformly dispersed nanoscale precipitates of sigma-phase was fabricated by high energy ball milling and spark plasma sintering. Microstructure and dry sliding wear performance against alumina at room temperature and 600 degrees C were then investigated. The matrix and the precipitates have the average grain size of 227 nm and 16 nm, respectively. Hardness was determined to be 707 HV. The epsilon-Co matrix, ultrafine-grained microstructure and the uniformly dispersed nanoprecipitates enable the alloy with excellent wear resistance. Grain growth of the matrix grain was found as the key factor to be responsible for the increase of wear rate at 600 degrees C. Subsurface microstructures of the alloy show no significant plastic deformation after wear tests, which is attributed to high hardness of the alloy and very limited slip in hcp system.
