Microhardness, corrosion behaviour and microstructures of directionally solidified Al-Cu alloys

The aim of this work is to analyze the effect of microstructural parameters (secondary dendritic arm spacings) on the microhardness and corrosion behavior of hypoeutectic Al-Cu alloys. Experimental results include HV microhardness values, corrosion and pitting potential and current density. It was f...
