Computational Thermochemistry for Modelling Oxidation During the Conveyance Tube Manufacturing Process

Metals
Conveyance tube manufacturing via a hot-finished, welded route is an energy-intensive process which promotes rapid surface oxidation. During normalisation at approximately 950 °C to homogenise the post-weld microstructure, an oxide mill scale layer grows
