Zirlo 피복관의 내압 크립 파열 특성

The creep burst tests of Zirlo claddings were performed in order to obtain high temperature deformation behavior and strength characteristics with testing temperature, which varying 350℃ to 600℃. Ultimate strength was in inverse proportion to temperature, strain rate was in proportion to stress. Rupture time and hoop strain was proportion to temperature. From this study, the criteria of fracture was suggested.
