Ultrasonic sent from self -designed ultrasonic device was used to influence solidification structures of steel C45 in experiments,and electric impulse generated from pulsed magnetic field device was employed to influence spring steel 60Si2CrVA before casting and 40 s after casting respectively.The results show that the mechanical properties of steel C45 are noticeably improved after ultrasonic treatment.For spring steel 60Si2CrVA influenced with pulsed magnetic field of 5 Hz/200 V before casting,isometric crystal ratio of the cast ingot is greatly increased to 74% from 49% when untreated by the magnetic field, and isometric crystal sizes are significantly reduced to 0.4 mm from 1 mm.For spring steel 60Si2CrVA influenced 40 s after casting,isometric crystal ratio is increased,and isometric crystal sizes are reduced with the increase of influence time.
