摘　　要：晶粒细化是提高材料强度和塑性,改善铸件质量的重要途径之一,其成功的关键在于形成高效、稳定、价廉的细化剂产品。在介绍Al-Ti-B合金晶粒细化剂的应用现状及生产方法的基础上,分析了晶粒细化剂的细化机理,明确了目前尚存在的问题,指出了今后的发展方向。Grain refinement is one of means of increasing strength and plastic of material, improving quality of casting, its success or not lie in manufacturing a high and long efficient and low price grain refiner. On the basis of study and application situation of Al-Ti-B grain refinement alloy and its classifications and production methods, refinement mechanism was detailed analyzed, and exiting problems and the development trends were pointed out.
