摘要
为克服钠盐及锶盐变质剂存在的问题，采用了钠锶复合盐作为共晶Ａｌ－Ｓｉ合金的长效变质剂。试验结果表明，该复合变质剂具有见效快、有效期长等特点。
In order to overcome the shortcoming of the sodium salt or the strontium salt,the sodium-strontium composite salt as a long-lasting modificator is adopted to replace the sodium salt or the strontium salt in eutectic Al-Si alloy.It shows by the experiment that the composite modificator can take effect quickly and its effectiveness can last for a long time.
