Abstract :
Magnetic hysteresis curves were simulated by the Monte Carlo method to study magnetic property changes under the sensitization of Ni base alloy, Alloy 600 (Inconel), which is well used as structural materials in nuclear power plants. Different distributions of spin concentration depending on heating duration time in cubic clusters caused to change the hysteresis curve. The calculation results agree with the experimental ones, and it suggests that the magnetic dynamic process can tell the degree of sensitization due to fatigue for Alloy 600 .
