| Abstract: | The effect of yttrium on the microstructure and properties of
Ti5.5Al3.5Sn3.0Zr1Nb03Mo03Si (IMI 829) and Ti14Al21Nb high temperature alloys was studied
by using optical microscope, SEM and mechanical property testing devices. The results show
that the microstructure and grains of the two alloys can be fined by adding yttrium. For IMI8290.
2Y alloy, the favorable mechanical properties at room temperature and creep properties at 550
are obtained, and the high temperature mechanical properties of Ti14Al21Nb0.1Y alloy are
improved as well. |
