文摘：The fatigue crack growth rate and CTOD tests on type 304 stainless steel
and weld metal were studied over the temperature range -162 degree C to room
temperature. The girth weld metal specimens were fabricated using a combination of
gas-tungsten-arc-welding and shielded-metal-arc-welding. The seam weld joint was
made by submerged arc welding. Fracture toughness was evaluated through CTOD tests
with three point bend specimens. The fatigue crack growth rate tests were conducted
using compact tension specimens in accordance with ASTM E647. The CTOD values were
affected by crack orientation with respect to the rolling direction, but orientation
had no influence on the fatigue crack growth rates. The fatigue crack growth rates
and the CTOD values decreased with decreasing test temperature. copy 2001 Elsevier
