摘要	The thermal stability of the rare earth-rich phase particles in alpha, alpha + beta and beta phase regions of Ti-5Al-4Sn-2Zr-1 Mo-0.25Si-1Nd(Ti-55) high temperature titanium alloy heat-treated was studied. Under conditions of 600 similar to 980 degrees C/1 similar to 100 h and 1050 similar to 1500 degrees C/1 similar to 10 h, the average particle size ranges from 3.34 to 4.20 mu m, the circularity shape factor from 0.619 to 0.759, and the volume fraction from 1.4% to 1.8%. The results show that nearly no change is found for the size, shape, and volume fraction of the particles in the alloy, and the rare earth-rich phase particles exhibit thermal stability.
