1Effect of Silver Content on Microstructure and Properties of Brass/steel Induction Brazing Joint Using Ag-Cu-Zn-Sn Filler Metal显示文摘The induction brazing of brass to steel using Ag-Cu-Zn-Sn filler metal was investigated in this study.The influence of Ag content on the microstructure and properties were analyzed by means of optical microscopy,scanning electron microscopy and electron probe microanalysis.Defect free joint was achieved using Ag-Cu-Zn-Sn filler metal.The microstructure of the joint was mainly composed of Ag-based solid solution and Cu-based solid solution.The increase of Ag content and the cooling rate both led to the increase of the needle like eutectic structure.The tensile strength decreased with the increase of Ag content.The tensile strength at room temperature using Ag25CuZnSn filler metal reached 445 MPa.All fractures using Ag-Cu-Zn-Sn filler metal presented ductile characteristic.J.

6Improving the hard magnetic properties by intragrain pinning for Ta doped nanocrystalline Ce-Fe-B alloys显示文摘To develop Ce based permanent magnets with high performance/cost ratio, Ta doping is was employed to enhance the magnetic performance of Ce-Fe-B alloys. For melt spun Cei7Fe78-xTaxB6 (x = 0-1) alloys, the coercivity Hc increases from 439 to 553 kA/m with increasing x value from 0 to 0.75. Microstructure characterizations indicate that Ta doping is helpful for grain refinement. A second phase of TaB2 is observed in Ce17Fe77.25Tao.75B6 alloy, which acts as the pinning center of the magnetic domains, resulting in the change of coercivity mechanism from nucleation type to nucleation +pinning type. The micromagnetic simulation confirms that non-magnetic particles within hard magnetic phase can increase the demagnetization field around them and it is crucial for preventing the further magnetization reverse by pinning effect. Take the advantage of Ta doping for enhancing the coercivity, Ce content of Ce-Fe-B alloy can be further cut down to increase the remanence Jr due to the reduced volume fraction of CeFe2 phase and increased Fe/Ce ratio. As a result, a good combination of magnetic properties with Hc = 514 kA/m, Jr = 0.49 T, and the maximum energy product (BH)max = 36 kJ/m^3 have been obtained in Ce15Fe79.25Tao.75B6 alloy. It is expected that the present work can serve as a useful reference for designing new permanent magnetic materials with low-cost.J.S.Zhang W. Li X.F. Liao H.Y. Yu L.Z. Zhao H.X. Zeng D.R. Peng Z.W.
