the localized corrosion behaviour of LY12CZ in 3% NaCl solution. Key words: LY12CZ; localized corrosion; intermetallic; applied stress; mechanochemical effect 1 Introduction Because of the characteristics... between stress and environment will furthermore enhance its sensitivity to the corrosions above (commonly we called this interaction of stress and environment as mechanochemical effect[1]). It is necessary......
alloy; intermetallics powder; solid-liquid reaction milling; mechanochemical effect 1 Introduction The effects of external fields such as the magnetic field, the electric field and the force field on the solidification behavior of melts induced much finer and more uniform solidification microstructures[1-3]. As a result, the mechanochemical field, which combines the force field with the chemical......
