Ultra-rapid freezing of Al and Al–Si12: Formation of nanocrystals and metastable solid solutions
We report effects of ultra-rapid melt–freeze cycles on pure aluminum and on aluminum alloy 4047 (which contains ≈12 at. % Si) caused by a series of ≈15 ns-long pulses of 308-nm laser light at a fluence of around 3 J cm−2. This process achieves a calculated cooling rate of about 109 K s−1, which is m...
