Rotating blades melt quenching: a kinetic analysis

A technique for the rapid solidification processing of alloy melts by rotat ing blades melt quenching (RBMQ) has recently been developed. In the presen t paper the kinetics of this process is explained by theoretical analyses, focusing on the impact force of the blade on the melt stream and the spread ing of the melt under this impact. The effect of melt properties and proces sing parameters resulting from theoretical calculations agree with experime ntal observations in the case of Al-Fe alloys. (C) 1999 Elsevier Science S. A.
