| Abstract: | Al--Bi immiscible alloy is an antifriction bearing alloy being studied. Using control- casting technique, Al--Bi alloys adding the third elements have been produced. The effects of adding the third elements, St, Sn and Ph on solidification structure of Al--Bi alloy have been studied. Melting at 1000 t, alloy ingots with uniformity were produced by control--casting techllique. Analysis of structure shows that the addition of third elements has strong effects on the size and appearance of Bi particles. |
