Abstract EN
Simultaneous vibration welding of 304 stainless steel was carried out with an eccentric circulating vibrator and a magnetic telescopic vibrator at subresonant (362 Hz and 59.3 Hz) and resonant (376 Hz and 60.9 Hz) frequencies.
The experimental results indicate that the temperature gradient can be increased, accelerating nucleation and causing grain refinement during this process.
During simultaneous vibration welding primary δ-ferrite can be refined and the morphologies of retained δ-ferrite become discontinuous so that δ-ferrite contents decrease.
The smallest content of δ-ferrite (5.5%) occurred using the eccentric circulating vibrator.
The diffraction intensities decreased and the FWHM widened with both vibration and no vibration.
A residual stress can obviously be increased, producing an excellent effect on stress relief at a resonant frequency.
The stress relief effect with an eccentric circulating vibrator was better than that obtained using a magnetic telescopic vibrator.
