| Abstract Scope |
The use of high strength, lightweight aluminum alloys in high-tech applications such as aerospace, as well as in the emerging field of electric vehicles, is an integral part of our society’s push towards high energy efficiency. However, solidification processing of such alloys, especially fusion welding and additive manufacturing remains challenging due to solute segregations and ultimately solidification cracking. Recently the use of refractory nanoparticles in hot crack susceptible aluminum alloys showed great potential to mitigate cracking during solidification. This work investigates the solidification mechanisms for aluminum alloy (AA) 7075 treated with a low volume fraction of nanoparticles. Using Differential Scanning Calorimetry (DSC) we showed a significant deviation in solidification behavior of nano-treated alloys from their commercial counterparts. |
