SECURING STABILITY OF A BLANK WITH POWDER IN HOT ISOSTATIC PRESSING TECHNOLOGY

摘要

The creation of a framework from sintered powder of the matrix material and squeezing a thin-wall blank tube by 1% under creep conditions together with stress reduction in the tube during preparation for pressing make it possible to fabricate cermet rods by hot isostatic pressing in a single stage without the blank losing stability. The penetration of fuel particles into the blank tubes is eliminated.
