Powder Size Influence on Tensile Properties and Porosity for PM Ti2AlNb Alloy Prepared by Hot Isostatic Pressing
Pre-alloyed powder of Ti 2 AlNb alloy was prepared by electrode induction gas atomization method, and the powder was screened into five kinds of powder size distribution. Fully dense Ti 2 AlNb alloy was prepared by powder metallurgy (PM) using hot isostatic pressing. The properties of pre-alloyed po...

2
AlNb alloy was prepared by electrode induction gas atomization method, and the powder was screened into five kinds of powder size distribution. Fully dense Ti
2
AlNb alloy was prepared by powder metallurgy (PM) using hot isostatic pressing. The properties of pre-alloyed powder and PM Ti
2
AlNb alloy were tested. Results show that mean grain size of PM Ti
2
AlNb alloy is influenced by powder particle size, but particle size has no significant influence on tensile properties. Finer Ti
2
AlNb 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 μm) are observed in PM Ti
2
AlNb alloy prepared by finer powder and cause plasticity loss of tensile properties. In order to get a better comprehensive properties of PM Ti
2
AlNb alloy, powder with an average size (~ 100 μm) is suggested. |
