摘要：
Damageability of turbine disk material, namely EI437BUVD and EI698VD alloys, in stress concentration zones (holes, grooves) is considered. It is shown that tests of natural-size specimens cut out from the zones of the greatest damageability enable one to ascertain the working capacity of the disks while taking account of the partial exhaustion of their life expectancy in the course of their long operation.
