The invention discloses a preparation process of high-Br and high-Hcj sintered neodymium iron boron without heavy rare earth, and belongs to the technical field of rare earth magnetic material preparation. The process comprises the following steps: raw material preparation and precursor preparation: weighing a main phase raw material and an Al-Ga-Cu ternary precursor according to a specific proportion; smelting, vacuumizing, filling argon, preserving heat at 1440-1460 DEG C, and adding a precursor; hydrogen decrepitation dehydrogenation reforming, wherein the temperature is increased to 845-855 DEG C for hydrogen decrepitation, and a parallel magnetic field is applied for dehydrogenation; key sintering is carried out, oxygen partial pressure is controlled to be 4-6 ppm, and the temperature is increased to 847-853 DEG C at a specific rate for sintering; low-temperature self-assembly is conducted, after the temperature is reduced to 600 DEG C, the oxygen partial pressure is increased to 14.5-15.5 ppm, heat preservation is conducted, and then the temperature is reduced to 400 DEG C; and the structure is locked, and the oxygen partial pressure is reduced to 4.5-5.5 ppm and then is cooled to 20-30 DEG C. Through a ternary precursor low-temperature self-assembly mechanism driven by an oxygen potential gradient, collaborative improvement of Br > = 1.45 T and Hcj > = 20 kOe under the condition of no heavy rare earth is realized, the grain boundary phase volume fraction is > = 85%, the problem of collaborative improvement of magnetic performance is solved, and the requirement of a high-end motor for a high-performance permanent magnet can be met.
