Potentiodynamic Corrosion Behavior and Microstructural Characteristics of Pulsed CMT‐Welded AA2014‐T6 Aluminium Alloy Joints: Effect of PWHT

open access: yesAdvances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
AA2014‐T6 is an Al‐Cu‐Mg‐based precipitation‐hardened aluminium alloy widely used in aerospace due to its high strength to weight ratio. This alloy is joined by a pulsed cold metal transfer (PCMT) arc welding process to overcome the high heat input related problems in gas metal arc welding (GMAW) such as a coarser dendritic structure in the fusion zone

Metallographic Investigation on Postweld Heat‐Treated0.21%C‐1020 Steel Plates Joined by SMAW Method

open access: yesAdvances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
This paper presents analysis and comparison into mechanical behaviour and microstructural attributes of postweld heat‐treated AISI 1020 (0.21%‐C) plates joined by the shielded metal arc welding (SMAW) process. The purpose of this work is to heat the welded samples uniformly so that a possible formation of austenite can be obtained, and hence, residual ...

Creep Rupture Behavior in Dissimilar Weldment between FB2 and 30Cr1Mo1V Heat‐Resistant Steel

open access: yesInternational Journal of Photoenergy, Volume 2021, Issue 1, 2021., 2021
Creep rupture behavior of dissimilar weldments between FB2 and 30Cr1Mo1V heat‐resistant steel by multipass welding at 783 K (510°C) under different stresses (260 to 420 MPa) was researched. The fitted creep rupture exponent is 14.53, and the 10,000 h extrapolating strength values predicted by the power law and Larson‐Miller parameter show good ...
