Phase relations for Fe-Ti-Zr ternary system at 1023K have been investigated by means of diffusion triple together with electron probe microanalysis technique, a series of tie-lines and tie-triangles have been determined and the isothermal section at 1023K has been established, and seven three-phase fields have been figured out. It was found that all of the Fe-Zr and Fe-Ti binary phases show large ternary solubility, and Zr and Ti can substitute for each other to a certain degree. The largest solid solubility of Ti in Fe2Zr and in FeZr3 is about 8.5 at.% Ti and 35.7 at.% Ti, and of Zr in Fe2Ti and FeTi is about 5.6 at.% Zr and 6.3 at.% Zr, respectively. The solubility range of Fe2Ti, FeTi, Fe2Zr and FeZr3 is 64.9 72.7 at.% Fe, 46.6-49.1 at.% Fe, 65.8-71.7 at.% Fe and 20.9-24.3 at.% Fe, respectively. No ternary compound was found.

The isothermal section of the phase diagram of the Co-Ni-Zr ternary system at 1198 K has been investigated by means of diffusion triple and electron microprobe analysis. This isothermal section consists of six threephase regions. The homogeneity ranges of Co23Zr6, Co2Zr, CoZr, Ni5Zr, Ni7Zr2 and NiZr are about 16.7%-18.8 at.%Zr, 28.6%-32.3 at.%Zr, 49.2%-51.7 at.%Zr, 16.0%-18.7 at.%Zr, 22.3%-24.1 at.%Zr and 49.8%-52.1 at.%Zr, respectively; CoZr2 and NiZr2 are nearly linear compounds. The largest olubilities of Ni in Co23Zr6, Co2Zr and CoZr are about 4.9 at.%Ni, 5.4 at.%Ni and 4.5 at.%Ni, respectively. CoZr2 and NiZr2 form a continuous solid solution (Co,Ni)Zr2. No ternary compound is observed.

FeZrN thin films with in-plane anisotropy were deposited on both rigid substrate Si and flexible substrate Kapton by magnetron sputtering. The as-prepared films had the microstructure of nanocrystallites with a small amount of intergranular amorphous phase. The thickness dependent coercivity showed different behaviors for flexible and rigid films. The dynamic magnetic properties of the films have been characterized. Although the high frequency characteristics are closely related to the thickness, composition, and anisotropy, the flexible films have relatively smaller values of real permeability but larger values of ferromagnetic resonance frequency fr than the rigid films. Due to the flexibility, the properties of the flexible films varied with each other. Nevertheless, both rigid and flexible films can find important applications in microwave absorber due to their excellent high frequency properties up to 5 GHz. © 2010 American Institute of Physics. doi:10.1063/1.3337684

采用单辊旋淬法，以不同的轮辊转速(50、40、30和25m/s)制备高Fe含量Fe82.65Cu1.35Si2B14非晶合金薄带，研究了冷却速度对快淬合金结构和性能的影响。结果表明：随冷却速度的降低，淬态Fe82.65Cu1.35Si2B14合金的条带厚度逐渐增大，合金由完全的非晶态结构转变为非晶与纳米晶的混合结构；同时，随冷却速度的降低，一次晶化温度下降，材料的饱和磁感应强度逐渐增加，在轮辊转速为25m/s时，淬态合金的饱和磁感应强度达到1.4T。
