Al-Ti-B细化剂和Al-10Sr变质剂对A357合金的联合作用
Effects of Combined Additions of Al-Ti-B Grain Refiners and Al-10Sr Modifier on A357 Alloy
摘要
Abstract
The effects of combined additions of Al-10Sr and Al-Ti-B grain refiners with two different Ti/B ratios on A357 alloy have been compared.The results show that under the condition of the same Sr amount,the refining effect of two Al-Ti-B master alloys on A357 alloy are enhanced with the increase of their addition amount within the scope of this study,the refining effect of Al-3Ti-3B is superior to Al-5Ti-1B with same addition level.Sr does not decrease the refining effect of two Al-Ti-B grain refiners.Al-3Ti-3B can can considerably weaken the Sr modification effect,the mechanical properties of A357 alloy with Al-3Ti-3B+Sr addition is lower than Al-5Ti-1B+Sr addition of same amounamountt.关键词
