摘要
采用等离子体发射光谱仪、光学显微镜、扫描电镜和X射线衍射仪检测分析了国内外Al-5Ti-1B合金线的化学成分、显微组织和晶粒细化效果。结果表明:韩国SLM公司Al-5Ti-1B合金线Fe、Si杂质元素含量较高,国内A厂Al-5Ti-1B合金线TiAl3尺寸较大,TiB2粒子团聚较严重,荷兰KBM公司和国内B厂的Al-5Ti-1B合金线的化学成分、显微组织和晶粒细化性能综合质量较好。
The chemical composition,microstructure and grain refining efficiency of Al-5Ti-1B alloy rods were investigated by ICP、OM 、SEM and XRD.Results show that the content of Fe and Si elements in Al-5Ti-1B grain refiner of SLM is higher than others.The size of TiAl3 and TiB2 agglomeration in Al-5Ti-1B grain refiner of domestic A factory are bigger than others.The comprehensive quality of Al-5Ti-1B alloy rods of KBM in Holand and domestic B factory arc the better.
