摘要
利用电子探针成分分析和X射线衍射分析等技术建立了Mo-Ru-Ti三元系的1100和1300℃等温截面相图。结果表明:在1100℃等温截面相图中存在3个三相区,而1300℃等温截面相图中存在2个三相区;在1100℃等温截面中,由于Ti的加入,σ-Mo5Ru3相被稳定化并形成一个小单相区;在1100和1300℃等温截面相图中,β(Ti,Mo)相均从富Mo侧一直延伸至富Ti侧,并且具有较大的固溶度。Mo-Ru-Ti三元系相平衡的测定为Ti基合金热力学数据库的建立提供了基础理论信息。
The isothermal sections of the Mo-Ru-Ti ternary system at 1100 and 1300℃were established using electron probe microanalysis and X-ray diffraction techniques.The results indicate that there are three three-phase regions at 1100℃isothermal section and two three-phase regions at 1300℃isothermal section;theσ-Mo5Ru3 phase is stabilized to 1100℃and forms a small single-phase region with the addition of Ti.Theβ(Ti,Mo)phase extends from Mo-rich side to Ti-rich side and dissolves a lot of Ru at 1100 and 1300℃.The phase relationship of Mo-Ru-Ti system will provide basic experimental data for the thermodynamic database of titanium alloys.
