Title: Damage structure in Nimonic PE16 alloy ion bombarded to high doses and gas levels

Abstract

The Nimonic PE16 alloy in solution-treated-and-aged condition was bombarded simultaneously with nickel ions and ..cap alpha.. and deuteron beams at 625/sup 0/C to doses of 80 to 313 dpa at He/dpa = 10 and D/dpa = 25. Microstructural changes consisted of the introduction of dislocations and of cavities, and the redistribuion of ..gamma..' precipitates to these defects. Cavitational swelling remained below 1%. Cavities were represented by several distinct size classes, the smaller ones believed to be gas bubbles, and some larger ones associated with preferred growth of precipitate. Formation of bubbles at grain boundaries, and large cavities at incoherent twins intensified the possibility of mechanical separation of interfaces under high-gas irradiation conditions.
