本文报道新型Fe_(72)Cu_1Nb_2V_2Si_(13)B_(10)和Fe_(72)Cu_1Nb_1Mo_1V_2Si_(13)B_(10)纳米晶合金的磁性能。直流起始磁导率μ_i的水平分别为138.16mH/m和113.04mH/m;矫顽力Hc水平分别为0.6和0.64A/m;对应H_m=0.08A/m和f=0.1和1MHz的相对有效磁导率μ_e水平分别为2.7×10~4,2.5×10~4和0.4×10~4,0.32×10~4;高频铁损水平分别为P_(3/100K)=612和730kW/m~3;P_(2/500K)=4260和5040kw/m~3;P_(0.5/1000K)=980和1090kw/m~3,这些都可与Fe-Cu-Nb-Si-B类纳米晶合金的相比,但大大优于优良的功率Mn—Zn铁氧体H_(7C4)的水平。
In this paper, the magnetic properties of novel Fe_ (72) Cu_1Nb_2V_2Si_ (13) B_ (10) and Fe_ (72) Cu_1Nb_1Mo_1V_2Si_ (13) B_ (10) nanocrystalline alloys are reported. The initial permeability μ_i of DC was 138.16mH / m and 113.04mH / m respectively; the coercivity Hc levels were 0.6 and 0.64A / m respectively; corresponding to H_m = 0.08A / m and f = 0.1 and 1MHz The effective permeability μ_e were 2.7 × 10 ~ 4, 2.5 × 10 ~ 4 and 0.4 × 10 ~ 4,0.32 × 10 ~ 4 respectively. The high frequency iron loss was P_ (3 / 100K) = 612 and 730kW / P ~ (2 / 500K) = 4260 and 5040kw / m ~ 3; P_ (0.5 / 1000K) = 980 and 1090kw / m ~ 3, Alloy, but much better than the excellent Mn-Zn ferrite H_ (7C4) level.
