Influence of Microstructure Evolution on Reheat by joining of W, V, Nb, Ti and B and the modification of C and Mo content.3) The Ti/N ratio must be set at least 3.5. T23 steel was suggested to be used with no preheat-ing nor post-weld heat treatment (PWHT). In recent years, reports on the PWHT cracking such as reheat cracking of T23 steel have increased.

Feb 07, 2021 · In previous studies, the impact of Ti and Cu addition on microstructure and toughness in simulated CGHAZ of low-alloy steels [15,16] and the localized corrosion behavior induced by inclusions, such as Al 2 O 3, MnS, were discussed in detail [29,30,31]. However, with addition of Ti, Cu, and Mn, the correlation between inclusion modification and The Effect of Chemical Composition on Microstructure and The current study investigates the effect of different levels of Ti, N, and Ti/N ratios on microstructure and properties in the intercritically reheated coarse-grained heat-affected zone (ICCGHAZ) of two-pass submerged arc welds in API 5L grade X70 pipe. Gleeble simulation was employed to reproduce the ICCGHAZ of actual welds. Hardness and Charpy V-notch (CVN)

The significant impact of Ti content on microstructure

This study aims to investigate the influence of Ti addition on microstructure and toughness in the simulated coarse-grained heated-affected zone (CGHAZ) of high-strength low-alloy steels. The steels with low and high Ti content respectively were subjected to 100 kJ/cm heat input welding thermal cycle. Weldability and toughness assessment of Ti-microalloyed The present study has been carried out to investigate the coarse-grained heat-affected zone (CGHAZ) microstructure and crack tip opening displacement (CTOD) toughness of grade StE 355 Ti-microalloyed offshore steels. Three parent plates (40-mm thick) were studied, two of which had Ti microalloying with either Nb + V or Nb also present. As a third steel, conventional StE 355 steel without Ti
