Abstract

The effects of the cooling rate (speeds of wheel surface v = 15 - 30 m / s in steps of 5 m/s) and composition 0 {less-than or slanted equal to} x {less-than or slanted equal to} 1 on the magnetic properties and microstructure of Nd₁₂Fe_71.4-xCo₁₀B_6.6Ga_x ribbons were studied. The coercivity H_c increases from 12 to 17 kOe when x increases from 0 to 1. The best magnetic properties of the ribbon after annealing were H_c = 17 kOe, M_r / M_s = 0.8, (BH)_max=18 MGOe with optimum cooper wheel speed of 25 m/s and x = 0.6.
