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

断裂韧度及疲劳裂纹增长
——304型液态天然气普通金属和焊接金属不锈钢传输管道的物理特性.
304型不锈钢和焊接金属材料在162度到室温环境下进行了疲劳裂纹扩展速率测试和CTOD（裂纹尖端张开位移）测试.
环形焊缝金属样本使用GTAW（钨电极惰性气体保护焊）和SMAW（保护式电弧焊）混合法进行测试.缝焊接口使用潜弧焊.通过三点弯曲试验,再用CTOD(裂纹尖端张开位移测试）对起断裂韧度进行评测.
疲劳裂纹扩展速率测试根据美国材料试验学会（ASTM）E647用紧凑拉伸试件进行测试.
轧制方向影响CTOD测试值,但不影响疲劳裂纹扩展速率.
疲劳裂纹扩展速率和CTOD测试值随测试温度的降低而递减.
