Abstract The molecular dynamics (MD) simulation method was adopted to explore impact of interface chemistry on pearlite mechanical response Bagaryatskii orientation relationship between ferrite and cementite. By changing terminal surface types cementite at ferrite-cementite interface, this study analyzed influence peak stress plastic deformation behavior, as well strain transmission two phases ...

The goal of this paper is to analyse the effect of adding Al on the non-steady pearlite growth occurring in a Fe-C-Mn system. The results are discussed in terms of the partitioning of elements across the austenite/ferrite and austenite/cementite interfaces, and the modification of the pearlite driving force related to the change in carbon activity in austenite.

The manufacturing of Dual-Phase steels includes as a crucial step the annealing cold-rolled ferrite-pearlite (F/P) microstructure, which involves numerous and interacting metallurgical mechanisms, namely recovery/recrystallization ferrite, globularization, manganese enrichment, coarsening cementite finally austenite transformation. Present study focuses on transformation considering its interac...

We report an attempt at increasing the thermal stability of nanocrystalline bainite to tempering heat-treatments, by enhancing the silicon concentration of the alloy. Validation experiments have been conducted using synchrotron X-radiation during tempering heat treatment. It is found that the change in alloying successfully stabilises the austenite at elevated temperatures by retarding cementit...
