Abstract

The effects of high amplitude ultrasound impact treatment on the structure transformations and corrosion behavior of manganese 16Mn-3Al austenitic steel have been investigated by X-ray diffraction, TEM and metallography methods. To evaluation of corrosion test results the weighing and microscopic methods as well as polarization curves one have been used. It was shown the ultrasound surface treatment leads to substructure and phase transformations in the steel. Under ultrasound effect the Fe3C and Fe23C6 carbides are forming as well as precipitation of carbon from solid solution and formation of twins. The ultrasound treatment enhances twice as much the corrosion resistance of steel. The interrelation between the substructure and corrosion resistance of austenitic steels as well as the method of increasing the corrosion resistance in materials with low energy of stacking faults were discussed.
