摘　　要：钛是铝及铝合金铸造时常用的晶粒细化剂,也是对晶粒细化最有效的元素之一,对某些铝合金还是一个微量合金化元素。钛剂与铝-钛-硼中间合金是常用的添加钛的载体,在钛价不甚贵的过去,多用钛剂,但在钛价高昂的今天,用Al-Ti-B中间合金不但经济效益更好一些,而且产品品质也更有保证。Ti is the grain refining agent that is commonly used in the casting of aluminum and aluminum alloy, one of the most effective element for refining grain,and a minor alloy element for some aluminum alloy. Ti agent and Al-Ti-B intermediate alloy is the common carrier to add Ti. Ti was used more in the past because of its low price. But now the price of Ti is so high that people use Al-Ti-B intermediate alloy more commonly to pursue more economic benefit and to guarantee better quality.
