摘要：
The room and high-temperature compression strength and ductility, microstructure, and fracture mechanism of Ni3Al base intermetallic doped with boron have been investigated. Ni3Al was produced by powder metallurgy (gas atomization and hot pressing), and vacuum melting and casting process. The strength of the material exhibits a positive temperature dependence with a maximum at approximately 700-degrees-C and then begins to decrease. The ductility remains practically unchanged up to 700-degrees-C and then increases significantly as the temperature increases. The ductility of Ni3Al cannot be correlated with fracture mechanism.
