N2 - The void swelling behavior of two molybdenum-base alloys, Mo -.5Ti and TZM, has been studied over a range of irradiation temperatures from 750 to 1450°C. Irradiation damage of up to 60 displacements per atom was produced with 3.1 MeV V ions. Standard transmission electron microscopy techniques were employed to analyze the irradiation induced microstructure. The predominance of data is from irradiations carried out between 850 and 1100°C. In this temperature range, swelling in TZM is approximately linearly dependent on dose, but independent of irradiation temperature. In contrast, Mo-.5Ti shows a distinct temperature dependence of swelling and swelling values higher than those for TZM. The influence of alloying additions, dislocation loop microstructure and grain size on swelling behavior is discussed.
