The Influence of Cooling Rate on Structure of EN AC 5083 Aluminum Alloy

Open access


In this paper it was studied the structure of EN AC 5083 aluminum alloy depending on cooling conditions. By cooling curves recorded for different casting conditions there were calculated the cooling rate (vr). The structural analyzes, performed by Image Pro-Plus 6.0 software, allowed both be highlighted structural particularities of various conditions for casting and establishing the correlation: lg d = lg v + n (where d is the dendritic parameter).
