THERMAL STABILIZATION TREATMENT AND THE EFFECT ON THE MICROSTRUCTURE IN DIRECTIONALLY SOLIDIFIED Ti-52%Al ALLOY
Thermal stabilization treatment with different treatment time and the corresponding directional solidification experiments are conducted for Ti-52%Al alloy in Bridgman-type directional solidified furnace. The formation of the mushy zone as well as the microstructure, interfacial morphologies and solute distributions o…
Preparation of Nanoscale Sm2Co17 Flakes by Ball Milling in Magnetic Field
A new preparation method of Sm2Co17nanoflakes was investigated.Hard magnetic Sm2Co17nanoflakes with thickness of 20-100nm were obtained by milling in heptane and oleic acid under a magnetic field of 1.5Tfor0.5-20h.It was shown that higher anisotropic magnetic properties would be induced by the flake-shape anisotropy w…
Effect of Oxidizing Concentration on the Corrosion Resistance of the Cerium Conversion Coatings on Galvanized Steel
Ce-based conversion films have been assessed as alternatives for replacement of Cr6+-based films,which have been forbidden for their toxicity and carcinogenic properties. However, corrosion protection associated with chromate films is difficult to achieve by other surface treatments. Experimental results have revealed…
Materials Data on Li6Fe3Co7O20 (SG:10) by Materials Project
Computed materials data using density functional theory calculations. These calculations determine the electronic structure of bulk materials by solving approximations to the Schrodinger equation. For more information, see https://materialsproject.org/docs/calculations
Effect of Rapid Heat Treatment on Bake Hardening Behavior of a Low Carbon Steel
A low carbon steel was firstly annealed with an ultra- rapid heating rate of 200℃/s at 660℃ and 750℃ respectively, then the steel was pre-strained to 2% and finally suffered a baking hardening treatment at 180℃ for 20 min in order to reveal the synergistic effect of the above two heat treatments of the performance of…
Density Functional Theory Study on Spin States of LaCoO3 at Room Temperature
在房间温度结构(293 K ) 的 perovskite LaCoO3 的电子结构被使用 PBE， PBE+U 和 HSE 计算。不同旋转配置被考虑了。我们的计算证明在在 HSE 的 DFT+U 和混合因素的 Hubbard U 参数的选择显著地象相对精力一样影响了乐队差距。因为旋转退出了状态，为 U 的最佳的价值并且是 3.0 eV 并且 0.05 分别地。当时，我们的计算也强调了那 U5.0 eV， PBE+U 将导致无理的电子结构和精力顺序。
