Autor: Best, James P., Kanjilal, Anwesha, Ghafarollahi, Alireza, Rehman, Uzair, Tian, Chunhua, Bishara, Hanna, Bhat, M. Kamran, Christiansen, Leon, Bitzek, Erik, Stein, Frank, Dehm, Gerhard

The cubic $C$15 CaAl$_2$ Laves phase is a crucial brittle intermetallic precipitate in Mg-Al-Ca alloys. Although knowledge of the mechanical properties of coexisting phases is essential for improved alloy design, the fracture toughness is not yet stu

Report

Preferred corrosion pathways for oxygen in Al2Ca-twin boundaries and dislocations

Autor: Peter, Nicolas J., Zander, Daniela, Cao, Xumeng, Tian, Chunhua, Zhang, Siyuan, Du, Kui, Scheu, Christina, Dehm, Gerhard

With an ongoing discussion on the oxygen diffusion along crystal defects remaining, it is difficult to study this phenomenon in Al containing intermetallic materials due to its rapid and passivating oxide formation. We report here the observation of
