The effects of microalloying with silicon and germanium on microstructure and hardness of a commercial aluminum alloy
Апстракт
The effect of small additions of Si and Ge on the microstructure and hardness was investigated during aging of a commercial 2219 aluminum alloy It was found that for the same level of microalloying in alloy 2219SG (containing St and Ge), a maximum hardness was achieved 3 times faster than in alloy 2219S (without Ge). The accelerated precipitation kinetics is a consequence of the presence of fine Si-Ge particles. serving as heterogeneous precipitation sites for theta strengthening particles.
