PROGRESS IN TIN ALLOY TECHNOLOGY

Abstract

THE equipment built at the Institute for research into the rapid solidification of tin alloys by melt‐spinning was successfully commissioned during the year and has been used extensively. The apparatus is capable of producing ribbon or flake from a jet of molten metal forced under gas pressure on to a wide bronze wheel rotating at circumferential speeds of up to 2000 m/min. The angle of attack of the metal stream, the clearance of the wheel by the crucible and the applied gas pressure may all be controlled so that various metal ribbon characteristics may be produced. The exact cooling rate for various alloys has not been measured but values of 106 deg C/sec are quoted by others as being attained with similar equipment. This produces very fine‐grained material which naturally shows changed mechanical properties in comparison with conventionally chill‐cast samples. However, no examples of amorphous material have yet been produced in work, which has concentrated so far on comparatively low melting point alloys.
