Investigation of fracture behavior of high strength aluminum alloys in the as-cast condition

Constitutive parameters, mechanical properties and failure mechanism in DC-cast AA7050 billets

Numerical simulation of residual thermal stresses in AA7050 alloy during DC-casting using ALSIM5

Non-homogenous cooling rates and solidification conditions during DC-casting of high strength aluminum alloys result in the formation and accumulation of residual thermal stresses with different signs and magnitudes in different locations of the billet. Rapid propagation of microcracks in the presence of thermal stresses can lead to catastrophic...

Application of a criterion for cold cracking to casting high strength aluminum alloys

Direct chill (DC) casting of high strength 7xxx series aluminium alloys is difficult mainly due to solidification cracking (hot cracks) and solid state cracking (cold cracks). Poor thermal properties along with extreme brittleness in the as-cast condition make DC-casting of such alloys a challenging process. Therefore, a criterion that can...
