Abstract
Abstract As a continuing investigation of the effect of carbon on void formation in metals, 4 MeV Ni++ ions were used to bombard three grades of nickel to 25 dpa at 594°C after helium implantation to 15 appm at room temperature. All irradiated specimens showed dense void formation irrespective of the carbon content. The present study thus reveals that the carbon effect disappears at high damage doses because too many vacancies are produced in comparison with the number of carbon atoms present in the matrix and also because the trapping of vacancies by the carbon atoms is not assisted by recombinations. Meanwhile, the dual-irradiated Ni specimens displayed unusual behavior of void formation and denudation along twin and grain boundaries. The one-side appearance of void denudation along many grain boundaries and the formation of unusually large voids at the edge of the denuded zone are particularly conspicuous and may have repercussions on the use of the denudation phenomenon to partially solve the swelling...
