| 1 | Microstructure and mechanical properties of B_4C-TiB_2-Al composites fabricated by vacuum infiltration显示文摘B4C-TiB2-Al composites were fabricated by infiltrating aluminum into porous B4C-TiB2 preforms in vacuum. The microstucture and mechanical properties of the B4C-TiB2-Al composites were investigated. The hardness decreased, the flexural strength increased, and the fracture toughness first increased and then decreased slightly with an increase in TiB2 content. The B4C-TiB2-Al composite with 40wt.% TiB2 showed the optimized properties. The infiltrated aluminum addition was the leading reason for the fracture toughness improvement of the composites. The tear ridges and dimples on the fracture surface of the composites increased gradually with the increase of infiltrated aluminum content showing inter/transgranular fracture mode. The relationships between the microstructures and the mechanical properties of the composites were discussed. | Lü Peng, YUE Xinyan, RU Hongqiang, and YU Liang Key Laboratory of the Ministry of Education for Anisotropy and Texture of Materials, Northeastern University, Shenyang 110004, China | 2010 | Rare Metals2010，29，1： | 2 |
| 2 | Preparation and Characterisation of Sr2CeO_4:Eu^(3+) Rare Earth Luminescent Material by High Temperature Mechano-Chemical Method显示文摘A novel, high-temperature, mechano-chemical(HTMC) method was developed to synthesise singlephase Sr_2CeO_4:Eu^(3+)phosphor. Phosphors were characterised by X-ray diffraction(XRD), scanning electron microscopy(SEM), and luminescence spectra. Compared with phosphors prepared by the traditional hightemperature solid state method and citric acid gel method, single-phase Sr_2CeO_4:Eu^(3+)powders by using the HTMC method, with small average particle sizes of about 5 μm, a narrow size distribution range and uniform dispersion, were prepared at 800 ℃, and reached their maximum luminescent intensity at 900 ℃.Under ultraviolet excitation at 298 nm, the sample showed good luminescence with the strongest red light of 616 nm. However, Sr_2CeO_4:Eu^(3+)was prepared at the higher temperature of 1100 ℃ by solid state method and citric acid gel method. The particle size was too large and uneven with phosphor agglomeration by high-temperature solid state method. The luminescent intensity reached a maximum for Sr_2CeO_4:Eu^(3+)phosphor at a synthesis temperature of 1100 ℃ by using the high-temperature solid state method, and at 1200 ℃ by both citric acid gel and chemical precipitation methods. Furthermore, the advantages of the Sr_2CeO_4:Eu^(3+)powder prepared by HTMC method were discussed compared with that prepared using traditional high-temperature solid state and citric acid gel methods. | Xue Yang Zhongbao Shao Hongqiang Ru | 2016 | Journal of Materials Science & Technology2016，32，10： | 2 |
