← TechnologyWhich outcome occurs when rapid cooling induces stress?
A)Quench cracking reduces component strength✓
B)Increased ductility prevents stress fractures
C)Homogeneous structure enhances material integrity
D)Stabilized grain boundaries improve corrosion resistance
💡 Explanation
Quench cracking arises because thermal contraction creates tensile stress surpassing fracture strength, therefore cracking is likely, rather than enhanced ductility, as rapid cooling stresses inherent flaws within the molecular structure.
