← ScienceWhich consequence arises from overfilling liquid nitrogen dewars made of austenitic stainless steel?
A)Paramagnetic behavior becomes ferromagnetic
B)Formation of stress-induced martensite✓
C)Susceptibility enhances nuclear magnetic resonance
D)Temperature exponentially decreases with depth
💡 Explanation
Stress-induced martensitic transformation occurs when the steel's face-centered cubic (FCC) structure changes at extremely low temperatures through lattice distortion. This happens because mechanical stress enhances ferrite phase change; therefore, martensite forms rather than retaining its austenitic microstructure.
