摘要
采用中频感应真空熔炼炉制备含Ti的脱氧剂45%Al-Fe-3%RE合金,并借助X射线、扫描电镜、能谱分析和硬度检测仪对合金铸态组织及硬度进行分析。结果表明,随着Ti含量(0,0.2%,0.3%,0.4%,0.5%)的增加,合金中的铸态组织晶粒得到明显的细化,并且组织更加致密;当Ti含量为0.3%时,合金的硬度最大,硬度值为HV 95。
45%Al-Fe-3%RE alloy containing Ti was prepared using a vacuum medium frequency induction melting furnace. The as-cast structure and the hardness of 45%Al-Fe-3%RE alloy was analyzed by X-ray diffraction,SEM, spectroscopy and hardness tester. The results show that the grains in the as-cast structure of the alloy are significantly refined and the structure is more compact with increasing Ti content(0, 0.2%, 0.3%, 0.4%, 0.5%)in the 45%Al-Fe-3%RE alloy. When Ti content is 0.3%, the hardness of the alloy is the maximum, with a hardness value of HV 95.
