Influence of Hydrogen on the Microstructures and Superplasticity of a Ti3Al-Nb Alloy

The effect of hydrogen on the microstructures and superplasticity of a Ti3Al-Nb alloy was studied. The results showed that hydrogenation made the volume fraction of B2 phase increase and facilitated the dynamic recrystallization of the lath-like phase. The addition of hydrogen. reduced the flow stresses and made the maximum m value move to a lower temperature during the superplastic deformation. The superplastic deformation temperature of the alloy can be lowered by about 60 ℃.     

LiFePO4/Li4Ti5O12锂离子电池的制备及研究

使用磷酸铁锂(LiFePO4)和钛酸锂(Li4Ti5O12)做正、负极活性材料,制备锂离子电池,并测试其性能。用三电极法考察不同配比时正负电极充放电电位的变化,并据此确定了电池中正负极的容量配比。性能测试结果表明,所制备的锂离子电池具有优异的循环稳定性,容量发挥好。正负极容量配比1.4时,18650圆柱电池负极钛酸锂的容量发挥为160mAh/g。     

石墨-钛酸锂复合阳极材料的制备及性能

利用石墨和钛酸锂复合材料作为锂离子电池的阳极活性材料,与磷酸铁锂阴极材料匹配制备了锂离子电池。制作的电池分别在充电曲线和放电曲线上出现两个平台,特别是第二个放电平台的出现,有助于降低过放对电池性能的影响。

Facile preparation and magnetic study of amorphous Tm-Fe-Co-Ni-Mn multicomponent alloy nanofilm

A facile and efficient synthesis route for the preparation of Tm-Fe-Co-Ni-Mn multicomponent alloy films was reported.Here the films with nanostructures were successfully synthesized by electrodeposition at room temperature.By changing the electrodeposition parameters,such as the deposition potential,deposition time,and the substrates,the styles of the nanostructures and surface morphologies of the deposits could be well controlled.The energy dispersive spectrometer (EDS) indicated that the five elements wer...
