摘要：

A series of Al-Cu-Si alloys were melted and spun into ribbons of about 100 m thickness. The alloy compositions were selected to be suitable for brazing below 580 C as filler metals. In the as-quenched state the foils were relatively brittle due to the occurrence of metal metastable phases. After appropriate annealing treatments between 400 similar to 450 C the metastable phases were transformed into fine (Cu2Al) particles within the -Al matrix, and the mechanical properties of the Al-Cu-Si alloy ribbons were considerably improved.
