Abstract
This study investigates the effect of electron beam welding (EBW) on SA508 Gr.3 Cl.1 Mn-Mo-Ni low alloy steel, focusing on changes in the microstructural and mechanical properties of the weld and heat-affected zone (HAZ) under various post-weld heat treatment (PWHT) conditions. The rapid cooling inherent in the EBW process led.....

DOI:
https://doi.org/10.3365/KJMM.2023.61.9.669
Abstract
A Fe-based filler material with the composition of Fe-20Ni-5Co-2.5Mn-0.2C was used for welding 9% Ni steel, and the effect of post-weld heat treatment on the microstructure and mechanical properties of the welded joints was investigated. Post-weld heat treatment of the welded joint was performed in the temperature range of 200.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.7.430
Abstract
In this study, the post-weld heat treatment (PWHT) cracking susceptibility in the heat affected zone (HAZ) of martensitic 10Cr steel was evaluated. The specimens taken from the 10Cr steel were thermally cycled using a Gleeble to simulate HAZ 1 (δ-ferrite) and HAZ 2 (single phase, γ). HAZ 2 had martensite.....
