WebNov 25, 2014 · Al-Ti-B master alloys are widely used in the aluminum casting industry for grain refinement.[1–5] The most widely used master alloy is Al-5Ti-1B (5 wt pct Ti, 1 wt pct B), which gives about 100 ppm of Ti and 20 ppm of B in the final castings.There are two kinds of particles in the master alloys, namely Al 3 Ti and TiB 2 in different particle sizes. WebFeb 1, 2015 · 1. Introduction. Grain refinement of Al alloys is desirable since it facilitates the casting process, reduces cast defects and therefore offers improved casting quality [1].To achieve a grain-refined cast microstructure, chemical inoculation by the addition of grain refiners has become a common industrial practice [2].The most widely used grain refiner … WebAl-Ti-B、Al-Ti-C中间合金细化铝及铝合金机制研究. 【摘要】： Al-5Ti-1B和Al-5Ti-0.2C是工业生产中最常用的两种铝合金中间合金晶粒细化剂，它们对铝合金良好的晶粒细化效果 … heart arrhythmia and dizziness
