Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020 In this study, the integrity of electron beam‐ (EB‐) welded CA6NM—a grade of 13% Cr‐4% Ni martensitic stainless steel—was assessed through the entire joint thickness of 90 mm after postweld heat treatment (PWHT). The joints were characterized by examining the microstructure, residual stresses, global mechanical properties (static tensile, Charpy impact,

International Journal of Corrosion, Volume 2018, Issue 1, 2018., 2018 We modified the content of rare‐earth elements (REE) in the flux‐cored wire used to produce welds of high‐strength low‐alloy (HSLA) steel. The effect of REE addition on the microstructure as well as on the mechanical and electrochemical properties of the welded metal (WM) was investigated. REE‐modified welded metals show very different responses during
