← ScienceWhich outcome occurs when thermally stressing a Shape Memory Alloy (SMA) undergoing actuation cycle?
A)Austenite grain growth accelerates
B)Critical stress induces martensite
C)Hysteresis loop area decreases
D)Transformation temperatures drift downward✓
💡 Explanation
An SMA experiences transformation temperature drift because repeated thermal cycling induces microstructural defects altering the energy barriers for martensitic transformation; therefore, the alloy's transition temperatures shift rather than maintaining stable points, under stress.
