Differential fast-scanning calorimetry and differential reheating as direct and indirect methods to study the critical cooling rates of Al-Zn-Mg-Cu alloys
2014
Preserved Fulltext
The precipitation behaviour during cooling from solution annealing of high alloyed aluminium alloy 7049A was investigated. This ranges from slowcooling with rates close to equilibrium up to rates above completesupersaturation and is covering seven orders of magnitude in cooling rate (0.0005 to 5000 K/s). The high alloyed, high strength and quench sensitive alloy 7049A has been investigated during quenching from solution annealing by conventional DSC in the cooling rate range 0.0005 – 4 K/s. A
