Description

Atom probe tomography and high resolution transmission electron microscopy have been employed to reveal clustering of Si and Ge atoms in ternary Al-Si-Ge. No such clusters were observed in binary Al-Si. The clusters were on the order of five nanometers in diameter and contained Si, Ge and Al. This confirms a previous hypothesis that postulates the existence of such clusters due to atomic mismatch strain compensation between the Si and Ge atoms in an Al solid solution
