Microstructural Changes, Tensile, and Hardness Behaviour of Welded Ti‐6Al‐4V Plates

open access: yesMaterial Design &Processing Communication, Volume 2024, Issue 1, 2024.
In this work, Ti‐6Al‐4V alloy was joined by tungsten inert gas (TIG) welding and the plates were undergone through optical microscopy test, elemental study, tensile test, hardness test, and fractographic observation. Plate‐A, with low value of current input, possesses α + β bimodal structure at BM, acicular martensite at HAZ, and Widmanstätten ...

Effect of PWHT on the Carbon Migration and Mechanical Properties of 2205DSS‐Q235 LBW Joint [PDF]

open access: yesAdvances in Materials Science and Engineering, 2018
The effect of postweld heat treatment (PWHT) on the carbon migration and mechanical properties of the 2205DSS‐Q235 laser beam welding (LBW) joint was investigated. The carbon‐rich zone (CRZ) and carbon‐depleted zone (CDZ) generated at the welding seam/Q235 (WS‐Q235) interface as the carbon migration occurred after heat‐treated at 600°C, 700°C, and 800 ...

Influence of welding procedure and PWHT on HSLA steel weld metals

open access: yesJournal of Materials Research and Technology, 2019
The development of consumables for welding of high strength steels represents a continuous challenge taking into account the great variety of alloy systems. In this regard, there are many applications, such as offshore structures, where the welding is still preferably done by the SMAW process. In order to evaluate the properties of weld metals obtained
