The crystallization behavior and microstructure of (Fe_0.9Co_0.1)_72.7Al_0.8Si_13.5B_9-xCu₁Nb₃Ti_x(x = 0,1,2) alloys were analyzed by the differential scanning calorimetry (DSC) and X-ray diffractometry (XRD). The soft magnetic properties of alloys after thermal treatment were studied by the temperature dependence of initial permeability (μ_i-T curves). Experimental results show that the proper addition of Ti can decrease the onset temperature of primary crystallization T_x1 for precipitating soft magnetic phase from 506 °C for x = 0–487 °C for x = 1 and increase the onset temperature of second crystallization T_x2 from 669 °C for x = 0–703 °C for x = 2. The extended onset temperature of second crystallization T_x2 of 703 °C and crystallization temperature interval ΔT_x of 199 °C make the 650^oC-annealed (Fe_0.9Co_0.1)_72.7Al_0.8Si_13.5B₇Cu₁Nb₃Ti₂ alloy exhibit superior magnetic softness at room- and high-temperatures. And the 610^oC-annealed (Fe_0.9Co_0.1)_72.7Al_0.8Si_13.5B₈Cu₁Nb₃Ti₁ alloy shows improved high-temperature magnetic softness at 450–650 °C with respect to Ti-free (Fe_0.9Co_0.1)_72.7Al_0.8Si_13.5B₉Cu₁Nb₃ alloy.
