Measurement of Local Strain Distribution of Austenitic Stainless Steels by Using Magnetic Sensors

Diagnosis of austenitic steel valves with the magneto-optical method

“…This could be expected, compared with the results in [1][2][3]. This is in connection with the transformation of the metastable phase g-Fe-a-Fe because of load during engine operation.…”

“…Tsuchida et al [3] measured remanence of austenitic steels dependent on deformation after a tensile-stress test, and they have shown that the highest increase in remanence appears in the point where the maximum deformation occurs. The next step in this field was the diagnosis of these materials using majority of hysteretic loops, and Takahashi et al [4] extended these works to minor loops as well.…”

Data Fusion From Multidirectional Remanent Flux Leakage Transducers for Nondestructive Testing of Stress- and Fatigue-Loaded Steel Samples

“…The quantities can be combined into one parameter , which represents the signal measured by ith transducer. The weights are then calculated using (2) where is the minimum value and is the maximum value of the parameter obtained for signals measured by each transducer for a tested sample. The , and are defined in the same way as in the first case.…”
