摘要：

Two double-wall windows of martensitic steel DIN 1.4926 were irradiated with 800 MeV protons at Los Alamos National Laboratory (LANL) to a total number of charged particles of about 6.3 x 10(22) protons (2.8 Ah) in a temperature range from 50 degrees C to 230 degrees C. The corresponding maximum fluence at beam centre was of about 2.6 x 10(25) p/m(2). Initial examinations on irradiation induced changes of hardness and microstructure have been performed. The preliminary results of microstructural investigation show that precipitates become amorphous after irradiation. There are no evident changes in precipitate size and compositions. Voids and helium bubbles are not observed. (C) 1999 Elsevier Science B.V. All rights reserved.
