Nb含量及固溶处理温度对TiAl基合金组织的影响

Effect of Nb Content and Temperature of Solution Treatment on Structure of TiAl Based Alloy

采用XRD定量相分析法对不同Nb含量及固溶处理的高Nb TiAl基合金中的相成分进行了测定和分析。随着合金中Nb含量的增加 ,或固溶处理温度的升高 ,合金中α2

The phases were quantitatively investigated via XRD in TiAl based alloys containing high Nb under the different Nb content and solution treatment.The results show that with the increment of Nb content or solution treatment temperature,α 2 phase content is increasing.
