Hot Tearing Susceptibility of AA3000 Aluminum Alloy Containing Cu, Ti, and Zr [PDF]

Metallurgical and Materials Transactions A, 2019
Abstract Severe hot tearing has been observed during DC casting of modified AA3000 alloys with additions of Cu, Ti, and Zr, although these alloys are regarded as rather easy to cast. Extensive studies have been performed on both synthetic and industrial AA2000, AA6000, and AA7000 alloys, but less data are available for AA3000 alloys.
