Published in 2024 at "Advanced Engineering Materials"

DOI: 10.1002/adem.202302083

Abstract: High‐rate dissolution process of Ti–48Al–2Cr–2Nb alloy in electrochemical machining exhibits strong nonlinear dynamic characteristics, but the quantitative relationship between these nonlinear characteristics and surface topography, as well as the electro‐dissolution mechanism, is unknown. Therefore, the… read more here.
