Glass Formability and Soft Magnetic Properties of Bulk Y-Fe-B-Ti Metals

The Ti effects on the glass forming ability and the magnetic properties of Y-Fe-B-Ti bulk metallic glasses have been investigated.Substituting 2 and 4 at% Ti for Fe or B in Y_6Fe_ 70B_ 22 alloys decrease the saturation magnetization(σ_s)and deteriorate the glass forming ability,respectively.However,substitution of 2 at% Ti for Y in Y_6Fe_ 72B_ 22 alloy induces larger supercooled region of 72.7℃,which not only makes the bulk glassy rod as large as 3mm in diameter,but also results in the superior soft magnetic properties of σ_s=126emu/g,coercivity(H_c)=0.2 Oe and Curie temperature(T_C)=268℃.Among all Y-Fe-B-Ti bulk amorphous rods,Y_4Fe_ 72B_ 22Ti_2 displays the best glass forming ability and also the proper soft magnetic properties.

Substituting 2 and 4 at% Ti for Fe or B in Y6 Fe20 B22 alloys decrease the saturation magnetization （a,） and deteriorate the glass forming ability, respectively. However, substitution of 2 at% Ti for Y in Y6 Fe72 B22 alloy induces larger supercooled region of 72.7 ℃ , which not only makes the bulk glassy rod as large as 3mm in diameter, coercivity （ Hc ） = 0.20e and Curie temperature （Tc） = 268℃ . glass forming ability and also the proper soft magnetic properties. but also results in the superior soft magnetic properties of a, = 126emu/g, Among all Y-Fe-B-Ti bulk amorphous rods, Y4Fe72B22Ti2 displays the best
