Defects introduced by helium irradiation at different temperatures in W and W-5wt%Re alloy

1Irradiation defects in w and W-5wt%Re alloys were characterized by DBS,TEM and SEM.2Re restricted the behavior of vacancy-type defects in tungsten.3The surface irradiation damage such as crystal gap enlargement, grain shedding and pores were observed at different irradiation temperatures.4The forma...
