经变形处理后的Al－5％Sr中间合金与未变形的相比，具有明显的变质效果差异在砂型条件下，用Al－5％Sr中间合金对共晶Al－Si合金进行变质处理，加入含锶量为0．1％的锭料，变质度为5级；加入变形处理的中间合金时，含锶量仅为0．05％时变质度为5级，含锶量为0．06％即达到最佳变质效果，为5.5级在金属型条件下，加入含锶量为0．06％的锭料与加入含锶量0.03％的变形处理的中间合金的变质效果相当，都为6级这种变质效果的差异是Al－5％Sr中间合金的组织遗传效应造成的
The deformed Al-5% Sr master alloy has obvious deterioration effect compared with that of the untreated one. Under the sand condition, the eutectic Al-Si alloy is modified with Al-5% Sr master alloy, When the amount of strontium is 0.1%, the degeneracy of the alloy is 5 grades. When adding the deformation-treated master alloy, the degenerating degree is 5 when the content of strontium is only 0.05%, the content of strontium is 0.06% That is, to achieve the best metamorphism effect 5.5 grade In the metal type conditions, the addition of ingot containing 0.06% of strontium content with the addition of 0.03% of strontium content of the deformation of the master alloy metamorphic effect, are 6 The difference in this metamorphism is caused by the tissue genetic effect of the Al-5% Sr master alloy
