Heating of Steel: Oxidation and Decarburisation | Metallurgy
This happens at low temperatures of heating (≈ 650 °C). But usually, the rate of decarburisation is higher than the rate of oxidation. The surface layer of steel beneath the scale loses its carbon, causing decarburisation and the surface may show only ferrite grains. Decarburisation is normally a harmful phenomenon.

At each time-point, there were more PPOs than PIMs; at baseline Māori were exposed to a significantly greater proportion of PPOs compared to non-Māori (p = 0.02). In Māori: PPOs were associated with a 1.5-fold increase in hospitalisations and mortality. In non-Māori, PIMs were associated with a double risk of mortality.

There is a linear relationship between specific input power and mill size in log-log scale, which indicates that P i is proportional to D n where n = 2.6 which is within the range reported in the experiments [3,35]. The result suggests that input power obtained from small scale mills can be extrapolated for large scale mills.

11 Common Welding Defects and How to Prevent Them ...
6. Overlap. Overlap occurs when the face of the weld extends past the toe of the weld. The filler material is unable to fuse to the base material as it flows over the extent of the weld joint and then cools down. The best preventative measure against the overlap welding defect is to ensure proper welding technique.
