← ScienceWhich outcome occurs when rapid cooling causes non-uniform crystal grain formation during steel manufacturing?
A)Reduced yield strength along grain boundaries✓
B)Increased magnetic coercivity alloy-wide
C)Enhanced oxidation resistance due to passivation
D)Higher thermal conductivity across the sample
💡 Explanation
Reduced yield strength occurs because, during rapid cooling, grain boundary segregation results from the Kirkendall effect due to differential diffusion rates. The crystal lattice is therefore weakened along these boundaries, rather than exhibiting enhanced oxidation resistance or altered magnetic behavior, because those involve other mechanisms.
