Grain and phase boundary segregation in WC–Co with TiC, ZrC, NbC or TaC additions
Jonathan Weidow,Hans-Olof Andrén +1 more
TL;DR: The microstructure of interfaces in WC-Co based cemented carbides with TiC, ZrC, NbC or TaC additions was analysed using energy dispersive X-ray analysis in a transmission electron microscope and using atom probe tomography as discussed by the authors.
Journal ArticleDOI
Modelling of temperature history and phase transformations during cooling of steel
TL;DR: In this article, a mathematical model based on the finite element method and additivity rule has been developed to predict temperature history and microstructural changes during cooling of steel, considering the effects of various factors including initial austenite grain size and its role on the kinetics of pearlite and ferrite transformations.

High strength ultrafine eutectic Fe–Nb–Al composites with enhanced plasticity
TL;DR: In this article, an enhancement of plasticity in high strength ultrafine eutectic Fe-Nb composites has been achieved by introducing heterogeneities in length-scale of the microstructure.

Secondary austenite and chromium nitride precipitation in simulated heat affected zones of duplex stainless steels
TL;DR: In this article, primary and secondary intragranular austenite precipitation and its relationship with chromium nitride (Cr2N) were studied in a simulated multipass heat affected zone (HAZ) of five duplex stainless steel alloys (UNS S32304, S32205, S32550, S32750, and S32760).

In-situ strengthening of a high strength low alloy steel during Wire and Arc Additive Manufacturing (WAAM)
Tiago A. Rodrigues,Valdemar R. Duarte,D. Tomás,J. A. Avila,J.D. Escobar,Emma Rossinyol,N. Schell,Telmo G. Santos,João Pedro Oliveira +8 more
TL;DR: In this article, SiC particles were added to the molten pool during WAAM of a high strength low alloy steel, and the introduction of these high melting point particles promoted grain refinement and precipitation of Fe3C due to SiC dissociation.
