摘　　要：研究了不同单一及复合微量高熔点Mn、Ti、Nb元素和Al-Ti-B细化剂对Al-5%Cu合金组织的影响。结果表明,不同微量高熔点合金元素单一加入对Al-5%Cu合金组织细化效果较好;复合加入较单一加入对组织细化效果更佳。The effect of single and complex trace high melting point elements of Mn, Ti, Nb and A1-Ti-B refiners on the microstrueture of Al-5%Cu alloy were studied. The results show that the microstructure refinement effect of A1-5%Cu alloy is better with single addition of different trace high melting point alloy elements. Compound addition has better effect on mierostrueture refinement than single addition.
