| Abstract | Pre-alloyed powder of Ti2AlNb alloy was prepared by electrode induction gas atomization method, and the powder was screened into five kinds of powder size distribution. Fully dense Ti2AlNb alloy was prepared by powder metallurgy (PM) using hot isostatic pressing. The properties of pre-alloyed powder and PM Ti2AlNb alloy were tested. Results show that mean grain size of PM Ti2AlNb alloy is influenced by powder particle size, but particle size has no significant influence on tensile properties. Finer Ti2AlNb powder has low Argon gas bubble ratio and high oxygen content, and poor flowability of finer powder increases the degree of difficulty during degassing. As a result, big pores (> 50 mu m) are observed in PM Ti2AlNb alloy prepared by finer powder and cause plasticity loss of tensile properties. In order to get a better comprehensive properties of PM Ti2AlNb alloy, powder with an average size (similar to 100 mu m) is suggested. |
