Melt Spinning of Crystalline Alloys

This paper describes the effect of melt-spinning process parameters such as orifice diameter, ejection pressure, and wheel speed, in determining the ribbon dimensions of Pb-Sn eutectic and low content A1 alloys. Rapid solidification techniques have been studied ever since the early experiments of Duwez et al. In recent years, the melt-spinning process (sometimes known as chill block casting) has been of particular interest because of the possibility of manufacturing iron-based amorphous alloys for magnetic applications. Liebermann and Graham and Kavesh have discussed the effect of melt spinning process parameters on the dimensions of melt-spun ribbons of amorphous Fe(40)Ni(40)B(20). This note describes the results of an investigation into the effect of melt spinning process parameters on the ribbon dimensions of two other materials, namely Pb-Sn eutectic and AL containing small quantities of Fe and Mn. The main objective was to determine whether the conclusions of Liebermann and Graham and Kavesh can be applied over a wide range of materials. Thus, Pb-Sn and AL-(Fe,Mn) were chosen because they have very different melting points from Fe(40)Ni(40)B(20), and because they solidify in a crystalline rather than amorphous form.
