We propose Monte Carlo simulations of the precipitation kinetics of NbC on dislocations in a-iron based on an atomistic description of the main mechanisms controlling the kinetic pathway. The algorithm takes into account realistic diffusion properties, with a rapid diffusion of C atoms by interstiti

## Abstract The results reported in this paper give new information regarding the early stages of precipitation in model low niobium steels. It clearly appears that the kinetic paths for carbides and nitrides precipitation in the investigated model alloys are very different, more continuous in the
A model Fe-30 wt% Ni, 0.1 C, 1.61 Mn, 0.1 Nb microalloyed steel, that simulates conventional microalloyed C-Mn steels, but does not transform from the austenite phase on cooling, is reported. Plane strain compression testing was undertaken at 950Β°C at a constant true strain rate of 10 s Οͺ1 . Samples
