Effect of cooling rate on corrosion properties and microstructure of high strength aluminium alloys

The Jominy end-quench test was applied to rods of the alximinium alloys T010 and X TO9I to obtain a decreasing cooling rate over the length of the rods. After heat treating to a high strength T6 and an overaged TT condition the corrosion properties and the microstructure were determined related to the cooling rate. No influence of cooling rate...
