Journal ArticleDOI
Effects of flux composition on the element transfer and mechanical properties of weld metal in submerged arc welding
TL;DR: In this article, the effects of wire/flux combination on the chemical composition, tensile strength, and impact toughness of the weld metal were investigated and interpreted in terms of element transfer between the slag and the welding metal, i.e., Δ quantity.
Journal ArticleDOI
Effects of nitrogen content and weld cooling time on the simulated heat-affected zone toughness in a Ti-containing steel
TL;DR: In this paper, an increase of nitrogen content in a 0.02 wt% Ti-containing carbon-manganese steel resulted in a low coarsening rate of TiN particles in the heat-affected zone (HAZ), which led to an accelerated ferrite transformation instead of ferrite side plates during weld cooling cycle.
Journal ArticleDOI
Comparison of the effects of fluorides in rutile-type flux cored wire
TL;DR: In this paper, the effects of fluorides on the arc stability, weld metal hardness, and microstructure were also examined, showing that the weld metal with higher slag basicities had a lower hydrogen content.
Journal ArticleDOI
Microstructure of reaction-bonded silicon nitride fabricated under static nitrogen pressure
TL;DR: In this article, reaction-bonded silicon nitride (RBSN) was fabricated using static nitriding system, where reactive nitrogen gas was supplied as a static state using computer-controlled gas delivery system instead of a dynamic flowing state.
Journal ArticleDOI
Evaluation of weld metal hot cracking susceptibility in superaustenitic stainless steel
TL;DR: In this article, the authors evaluated the susceptibilities of two types of superaustenitic stainless steel, namely, 254SMO and SR50A, to solidification cracking by transverse Varestraint tests.
