Low Temperature Fracture Behavior of Iron-Nickel Alloy Steels
SourceFracture toughness tests over the interval 298 to 4 K and fatigue crack growth rate tests at 298, 111, and 76 K are reported on selected iron-nickel (Fe-Ni) alloys which are commercially available for potential use in storage or transportation of liquefied natural gas (LNG). These alloys include Fe-6Ni and Fe-5Ni in newly developed three-step heat treatments and Fe-9Ni in the quenched and tempered condition. Linear elastic fracture mechanics parameters (KQ, KIC) and J-integral (JIC) test data are presented for 1.25-in.-thick compact specimens. Discussion includes comparisons of fatigue crack growth rate and fracture data between alloys.
