Owing to the findings of new locations for crude oil and natural gas, the need of high
strength materials that can be used for pipes and their joining has gained paramount …

Stress corrosion cracking (SCC) behavior and mechanism of E690 welded joint in simulated
marine atmosphere containing SO 2 were investigated using SSRT method and …

Varying cooling rates are used to investigate the influence of martensite-austenite (MA)
microconstituent on the mechanical properties of X80 linepipe steel after intercritical …

Purpose The key purpose of conducting this review is to identify the issues that affect the
structural integrity of pipeline structures. Heat affected zone (HAZ) has been identified as the …

In the present study, the simulated coarse-grained heat-affected zones (CGHAZs) of X90
pipeline steel were produced using a Gleeble 3500 simulator under different heat inputs …

The microstructure and mechanical properties of welding heat affected zone (HAZ) of three
typical X80 pipeline steels, ie Mn–Cr–Nb, Mn–Mo–Nb and/or Mn–Cr–Mo–Nb steels, have …

Local brittle zones, ie., martensite–austenite (M–A) islands, are formed within the coarse-
grained heat-affected zone (CGHAZ) and the intercritically reheated CGHAZ (ICCGHAZ) …

In this work, the impact fracture of coarse grain heat-affected zone (CGHAZ) of an X80 steel
weld with various heat inputs was investigated in the absence and presence of hydrogen (H) …

The thermal cycles that high strength low alloy (HSLA) low carbon steels experience during
welding inevitably affect the microstructure and mechanical properties of the weld joints. It is …

The microstructures, mechanical properties and fracture toughness of the materials in
different locations of the welded joint of the X80 pipeline steel were studied at room …
