bibo:abstract
  • Creep-fatigue crack growth behavior at the heat affected zone of lCr-0.5Mo steel weldment has been experimentally studied. Load hold times of the tests for trapezoidal fatigue waveshapes were varied among 0, 30, 300 and 3,600 seconds. Time-dependent crack growth rates were characterized by the <TEX>$$C_t$$</TEX> estimated with the equation proposed by the previous finite element analysis work. It was concluded that the <TEX>$$C_t$$</TEX> values calculated from the properties of parent metal were quite comparable to the accurate <TEX>$$C_t$$</TEX> values calculated from both of weld and parent metals. Scatter of data was claimed due to the difference of exact location of the cracks in HAZ. The cracks have a tendency to change their path from the original location eventually to the relatively soft HAZ(ie, near-FGHAZ region, fine grained heat affected zone). (rdf:langString) (en)
