摘要

在铝硅合金中加铅（Ｐｂ）、硼砂（Ｎａ２Ｂ４Ｏ７·１０Ｈ２Ｏ），考察其对铸态组织的影响。试验表明：铅有变质作用，加入０．８％～１．０％Ｐｂ，可得到典型的变质组织。硼砂有细化晶粒和变质的两重作用；再加入一些物质，可能成为一种新型的复合处理剂。

Abstract

The effects of lead and borax on the casting structure were investigated. The resultsshow that typical modified structure was obtained when 0. 8% ～ 1. 0% lead was added. Borax hasthe functions of modification and refining grain. If some other substances were added

a new kindof compounded additive may be obtained.
