Open AccessMicroanalysis of TiN phases formed in inclusions of electrogas weld metal
This study has been conducted to confirm the formation of TiN phase in the electrogas (EG) weld metal and, if it formed, to identify the nucleation potency of TiN for acicular ferrite. To facilitate this, a hi...

Nature of nonmetallic inclusions in electrogas weld metal
An electrogas weld metal deposited with an approximately 20 kJ/mm heat input was examined to investigate the chemical and microstructural characteristics of nonmetallic inclusions related to the weld microstru...

Characterization of the local brittle layer formed in electro-gas weld metals
The microstructural characteristics of the local brittle layer (LBL) reported to be formed at the weld center of tandem electro-gas (EG) weld made with EG70T-G wire have been investigated to identify the criti...

Effect of Post Weld Heat Treatment on Cryogenic Mechanical Properties of Electron Beam Welded Cast Inconel 718
Electron beam welding of pre-aged cast 718 produced a slender Laves phase, while welds from solutionized cast 718 exhibited a blocky Laves phase with an initial stage of δ precipitation and formation of γ′+γ″ ...
