摘要：
The phases of as-forged W-1%La2O3 alloy, especially the nano-sized particle phases, have been investigated using transmission electron microscopes. We find 8 kinds of particle phases in the alloy, which are 3 kinds of La2O3 phases, 2 kinds of WO3 phases, W3O8 phase, La0.14WO3 phase and (La2O3)5WO3 phase. La2O3, WO3 and W3O8 are dominant nano-sized phases in the alloy. These particle sizes range from 20 nm to 100 nm. The possible formation processes of these particle phases were also discussed. © 2016, Science Press. All right reserved.
