Abstract
Aluminum alloys in a rapidly quenched state are studied by four technological methods, namely, fabricating foils and wire with unique properties, fabricating granulated alloys, surface strengthening and alloying articles by a laser or an electron beam treatment, and realizing superplasticity. In rapid quenching of alloys, crystallization occurs with cooling the melt at a rate of at least 103–104 K/sec. Such cooling can be realized in practice by several methods, for example, by drop crystallization on a rotating heat-conducting substrate, spraying of the melt in a cooling medium, quenching a thin foil on cooled rolls in liquid rolling, or melting a thin surface zone of a quite massive part. The present paper describes a study of flakes of aluminum alloys obtained by the method of drop crystallization.
