摘要

研究了Al-5Ti-1B和Al-3Ti-0.15C两种细化剂对2026铝合金铸锭组织、型材组织及型材性能的影响。结果表明

在0.2%的添加量下

Al-5Ti-1B细化剂的细化效果优于Al-3Ti-0.15C细化剂

采用Al-5Ti-1B细化剂生产的铸锭和型材的晶粒尺寸均小于对比试样;采用Al-5Ti-1B细化剂生产的型材强度略高于采用Al-3Ti-0.15C细化剂生产的型材

但伸长率略有降低。

Abstract

The effects of two imported refiners

Al-5Ti-1B and Al-3Ti-0.15C

on the microstructure of 2026 ingots and extrusion profile as well as extrusions properties were investigated.The results reveal that the refinement effect of Al-5Ti-1B grain refiner is better than that of Al-3Ti-0.15C grain refiner at the same amount of 0.2% addition.The grain size of ingots and extrusions adding Al-5Ti-1B grain refiner is smaller than that of the comparative sample.The strength of extrusion profile adding Al-5Ti-1B grain refiner is slightly higher than that of one adding Al-3Ti-0.15C grain refiner

while the elongation is reduced slightly.
