The influence of alloy elements on dc and ac magnetic properties of Fe79M2Si6B11C2(M is V, Mo or Cr) amorphous alloys was investigated. The variation law of the magnetic properties and the loss with the different elements was studied. The results show that the addition of V, Cr or Mo elements reduces the saturation magnetic induction in varying degrees. The addition of V element increases the permeability, decreases the coercivity and drops the loss. The addition of Cr and Mo reduces the permeability, and increases the coercivity.

The variation of the magnetic properties of the nanocrystalline alloys for the partial substitution of V for Nb with crystallizing treatment temperature and time was investigated. The variation law of the magnetic properties with the annealing temperature and time is essentially the same. The magnetic properties of the Fe-based nanocrystalline alloys for the partial substitution of V for Nb reduce, and the crystallizing treatment temperature of the alloys increases. The optimum properties of Fe74Cu1Nb3Si13B9 nanocrystalline alloys crystallized at 550℃x60 min are μ0=9.2xl0^4, μm=54.8xl0^4, Hc=1.14 A/m and Bs=1.26 T. The best properties for Fe74Cu1Nb3Si13B9 alloys annealed at 560℃x60 min are μ0=8.79x10^4, μm=50.18xl0^4, Hc=1.26 A/m and Bs=1.24 T.

In this article, the quenched Nd_4.5Fe_75Co_1Si_l B_18.5 ribbons were prepared, and the structures and properties were investigated. The results show that the change of structures of Nd_4.5 Fe_75 Co_1 Si_1 B_18.5 quenched amorphous ribbons is Am→Am'+Fe_3B+Nd_2Fe_23B_3+Nd_2Fe_14B→Nd_2- Fe_14B when it is heated. The effect of crystallizing treatment temperature and time on the magnetic properties of the quenched alloy was studied. The magnetic properties of 16 m/s quenched ribbons for 710℃×1200 s crystallizing treatment reach _iH_c=238.6 hA/m, B_r=0.8987 T and (BH)max=51.39 kJ/m^3. The grain size is about DFe3=32 nm and DNd2Fe14B=22 nm.

The effect of Cu addition on the spinodal decomposition of the Al-Zn alloy with symmetrical compositions has been investigated by X-ray diffraction analysis. It is found that the single fcc phase can be obtained in the AlZn alloy with the addition of 2 at. pct Cu after solution treatment at 400℃ and water quenching to room temperature. The modulation structure occurs in two types of alloys aged at room temperature for 30 min. The spinodal process remarkably slows down above or at the three phase equilibrium temperature, particularly at room temperature due to the addition of 2 at. pct Cu. The spinodal time increases by 20 times when aging at 300℃ and by more than 30 times when aging at room temperature.
