| 2 | Oxygen Permeation Behaviors and Hardening Effect of Titanium Alloys at High Temperature显示文摘In order to improve the surface hardness and wear resistance of Ti and Ti alloy components, an oxygen permeationtreatment (OPT) was developed. The oxygen permeation behaviors of three Ti alloys, TA2, TB5 and TC11, treatedin air with O-P medium at high temperature have been studied. The results show that the O-P treatment cansignificantly improve the surface hardness of Ti alloys. The oxidation mass-gain of β-Ti alloy (TB5) is much higherthan α-Ti alloy (TA2) under the same condition, while α+β Ti alloy (TC11) is the lowest. All the Ti alloys treatedat this condition produce two surface layers: the outer layer consists mainly of TiO2, as well as trace of other oxides,and the inner layer consists of a Ti-O interstitial solid solution formed by the diffusion of oxygen in α crystal latticeThick scales of β Ti alloy (TB5) are easily formed depending mainly on the poor solid solution content of oxygen,while deep solution layer can be formed since partial β phase has been transformed into α phase. The scales of α-βTi alloy (TC11) are very thin and compact. Aluminum-rich zone, as well as deficient zone, is found in oxide layerrs.A crystallographic characterization of oxygen solution layer has been performed and evaluated by crystallographiclattice constant. | Hongyan MA, Maocai WANG and Weitao WUState Key Laboratory for Corrosion and Protection, Institute of Metai Research, Chinese Academy of Sciences, Shenyang 110016, ChinaGraduate School of the Chinese Academy of Sciences, Beijing 100039, China | 2004 | Journal of Materials Science & Technology2004，20，6： | 3 |
| 3 | Effect of annealing time on the exchange coupling interactions and microstruc-ture of nanocomposite Pr_(7.5)Dy_1Fe_(71)Co_(15)Nb_1B_(4.5) ribbons显示文摘The influence of annealing time on the magnetic properties and microstructure of nanocomposite Pr7.5Dy1Fe71Co15Nb1B4.5 ribbons was systematically investigated by the methods of vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). Interaction domains derived from strong exchange coupling interactions be- tween hard and soft magnetic grains were imaged using magnetic force microscopy (MFM). Maximum remanence, intrinsic coerciv- ity, and maximum energy product values were obtained in the ribbons annealed at 700°C for 15 min, which were composed of Pr2(Fe, Co)14B, α-(Fe, Co), and slight Pr2(Fe, Co)17 phases. Although Jr, Hci, and (BH)max decreased gradually with further increase of an- nealing time, it is emphasized that comparatively high Jr and Hci and (BH)max were obtained in a wide annealing time period of 15 to 360 min. The shape of initial magnetization curves and hysteresis loops change as a function of annealing time, indicating different magnetization reversal routes, which can be fully explained by the corresponding microstructure. | Xiaoqian Bao Yi Qiao Xuexu Gao Maocai Zhang Jie Zhu Shouzeng Zhou | 2007 | Journal of University of Science and Technology Beijing2007，14，6： | 3 |

It has been found that the magnetostrictive strains of polycrystal samples with [110] axial orientation can reach (1550-1900) ×10^-6 in a low magnetic field less than 80 kA/m, which are equal to or somewhat better than that of the polycrystal samples with [112] axial orientation. | Shouzeng ZHOU, Xuexu GAO, Maocai ZHANG, Qing ZHAO and Zhenhlla SHI (State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China) | 2000 | Journal of Materials Science & Technology2000，16，2： | 2 |
| 6 | Laser cladding of Al+Ir powders on ZM5 magnesium base alloy显示文摘Laser cladding of preplaced Al + Ir powders on a ZM5 magnesium alloy was performed to enhance the corrosion resistance of the ZM5 magnesium alloy. A metallurgical bond was obtained at the coating/substrate interface. The corrosion potential (Ecorr) of the laser cladded sample was 169 mV positive to that of the untreated ZM5 substrate,while the corrosion current (Icorr) was some one order of magnitude lower. The laser cladded sample,unlike the untreated ZM5 substrate,showed a passive region in the polarization plot. Immersion tests confirmed that the corrosion resistance of the laser cladded ZM5 sample was significantly enhanced in 3.5 wt.% NaCl solution. The Al-rich phases of AlIr,Mg17Al12,and Al formed in the cladding layer and the rapid solid characteristics were contributed to the improved corrosion behavior of the coating. | CHEN Changjun WANG Maocai WANG Dongsheng JIN Ren LIU Yiming | 2007 | Rare Metals2007，26，5： | 2 |
