Investigation of the Fe_{60}Co_{13}Zr_1Ti_3Pr_9B_{14} alloy 1 mm diameter rods and 3 mm outer diameter tubes showed a possibility of processing nanocrystalline magnets by direct quenching. It was revealed that the low temperature annealing of the tube samples at 573 K/10 min resulted in an improvement of the intrinsic coercivity that reaches≈1260 kA/m, which was a similar value to that measured for thin ribbon annealed at 973 K/10 min. The X-ray diffraction analysis revealed that the hard magnetic Pr_2(Fe, Co)_{14}B was the single crystalline phase that precipitated during rapid solidification process of the tube and rod samples and during devitrification annealing of the ribbons.
