摘要：

Most of spherical blisters formed by deuterium (D) bombardment (38 eV/D) up to 3 x 10(24) D/m(2) at 300 K on polycrystalline tungsten are fully elastic deformations. This has been proven by opening individual blisters with a focused ion beam and in situ observation of their complete relaxation by scanning electron microscopy. The D-2 gas filling is confirmed by observing simultaneously the D-2 puff. The gas pressure is causal for the stability of such spherical blisters after implantation and the gas release leads to sudden relaxation. The dilatation of the blister cap by trapped D can be excluded as cause for the blisters. (C) 2011 Elsevier B.V. All rights reserved.
