Ion irradiation studies on the void swelling behavior of a titanium modified D9 alloy

Effects of Titanium and Silicon on the Swelling Behavior of 15–15Ti Steels by Heavy-Ion Beam Irradiation

“…It has been revealed that titanium plays an important role in determining the irradiation behavior of austenitic steels [4][5][6]. The resistance to swelling of austenitic steels was obtained when cavity nucleation and growth were suppressed.…”

“…Consequently, cavity swelling is considered to be the main life limiting factor of the fuel pins. So the resistance to swelling is the major consideration in screening cladding materials [3][4][5][6]. Swelling during irradiation depends sensitively on the prior microstructure of the alloy.…”

“…Minor alloying elements, such as titanium and silicon, could play crucial roles in forming fine stable precipitates [4,5]. Although the effects of alloying elements on the swelling of 15-15Ti steel have been widely investigated, there are distinct differences in the alloy composition and the corresponding properties in the different reports [3][4][5][6][7][8][9]. To attain the good resistance to swelling, it is necessary to understand the synergistic effects of alloying elements on the swelling behavior of the 15-15Ti steel.…”

“…To attain the good resistance to swelling, it is necessary to understand the synergistic effects of alloying elements on the swelling behavior of the 15-15Ti steel. Heavy-ion beam irradiation has been thought to be an indispensable tool for screening alloys and evaluating basic process on the basis of their swelling behaviors [6,10]. One of the methods for swelling estimation in heavy-ion irradiation experiments is direct observation of the cavities by transmission electron microscopy (TEM) [11].…”

Development of a simple, low cost, indirect ion beam fluence measurement system for ion implanters, accelerators

“…The system is more suited for the electrostatic accelerators and ion implanters where the ion beam is continuous and stable. With the development of this automated system, a number of ion implantation/ion beam analysis experiments relating to radiation damage in metals and alloys [7,8] were successfully carried out in an advanced dual beam ion irradiation facility whose lay out is shown in figure 1 with the least requirement of human intervention apart from achieving very good accurate results and increased experimental throughput. The dual beam ion irradiation facility, in which an indigenously built 400 kV accelerator is used for injecting Helium/Hydrogen and a 1.7 MV Tandetron accelerator is used for irradiation by heavy ion beam which produces displacement damage at very high rate, was set up to simulate synergistic effects of displacement damage and gaseous helium/hydrogen which is important in the context of development of radiation resistance materials for fast fission, fusion and accelerator driven subcritical systems.…”
