Connection between hot tearing and cold cracking in DC-casting of AA7050: Experiments and computer simulations

Direct-chill (DC) casting is one of the most common methods to produce ingots of high-strength aluminum alloys such as an AA7050. Despite of its superior mechanical properties, this alloy is prone to both hot tearing (HT) and cold cracking (CC) during DC casting. HT form above the solidus while CC occurs below the solidus temperature. CC...
