다국어 초록 (Multilingual Abstract)

The physical properties of(Fe_1-xSi_x)_99B₁alloys fabricated by rapid quenching technique have been studied systemetically by means of a vibrating sample magnetometer, a D.C magnetic hysteresis loop tracer, an eletrical resistance measurement apparatus, a X-ray diffractometer and a vicker's hardness tester. The results are as follows;
1) Saturation magnetization decreases linearly from 210 emu/gr (x=0.03) to 192 emu/ gr (x=0.7) with increasing Si-concentration.
2) Coercive force decreases from 13 Oe (x=0.03) to 6.5 Oe (x=0.06) and then increases to 13.5 Oe (x=0.07) with increasing Si-concentration.
3) Electrical resistivity increases linearly from 57 μΩ-cm to 110 μΩ-cm with increasing Si-concentration and in the rapidly quenched state is about 10% as large as that for the crystallized state(after heated to 1200 K).
4) Vicker's hardness increases from 210 kg/mm²(x=0.03) to 470 kg/mm²(x=0.07) with increasingg Si-concentration. The hardness of the rapidly quenched alloy is less than that of the mother alloy by approximately 80kg/mm².
