Which consequence results when a blacksmith over-heats steel during forging?

💡 Explanation

Grain boundary oxidation increases because overheating promotes diffusion of oxygen into grain boundaries, forming oxides; therefore, the component weakens where there is little ductility, rather than increases in stiffness, or optimized microstructure which require careful heat treatment instead.
