← HistoryDuring China's iron age, which outcome occurred as crucible steel introduced greater carbon homogeneity?
A)Ironwork became brittle at edges
B)Blade edges sustained greater impacts✓
C)Crucible's wall developed micro-fractures
D)Alloy transformation become exceedingly difficult
💡 Explanation
The crucible steel process promoted uniform carbon diffusion, thus the resulting microstructure improves resistance to deformation by work hardening rather than embrittlement, because homogenous cementite distribution imparts toughness, therefore the material becomes harder, rather than other localized structural defects.
