1. Pb particles were observed both within Al matrix grains and at grain boundaries. The size of these particles is ∼200 nm.
2. -1), a ductile-brittle transition was observed at temperatures between 320 and 330°C, within which liquid Pb begins to form at grain boundaries. This promotes grain-boundary cavitation and, thus, premature failure.
3. -1), even at temperatures above the melting point of Pb, grain-boundary cavitation is greatly suppressed and ductility significantly increases. In this case, the fracture of sample is determined by neck instability.
