| Abstract: | The heat treatment process investigation of 45 steel semiaxis bush was performed by means of orthogonal test.The effect of austenitizing temperature , holding time, quenching medium and swing of the semiaxis bush during the quenching on the microstructure and hardness were studied .The results show that the optimum heat treatment process of the semiaxis bush consists of heating at 860℃for 60 min and quenching in 8%NaCl aqueous solution , swinging the semiaxis bush now to the left and now to the right during the quenching . |
