Abstract

PURPOSE:To add additive materials without the formation of coarse grains of fined primary crystal Si and to improve abrasion resistance and machineability by adding the additive materials to a find high Si-Al alloy under agitation in a semi-molten state. CONSTITUTION:A high Si-Al alloy is melted and is cooled quickly to form an alloy base metal wherein the primary crystal Si in the alloy is fined. Next, this alloy base metal is put in a graphite crucible where it is heated to its eutectic temp. or below and is held in a semi-molten state. Graphite powder is added to this under agitation, In this way, the primary crystal Si is maintained in a fine state simply by controlling its temp., and the high Si-Al alloy is formed to the structure wherein its components and additive materials are uniformly dispersed and contained.
