These were similar to those of the failed samples in the field.
Failed samples were examined under scanning electron microscope at different magnifications to analyze their fractured surfaces.
Fracture surfaces of the failed samples were analyzed to determine the failure modes.
The failure modes and mechanisms found experimentally were similar to those of the failed samples returned from the field.
The failure modes and mechanisms found experimentally were identical to those of the failed samples in the field.
Pokkali and two RILs were declared as failed samples for having less than 10%% of the mean reads per sample.
The metallography of the failed samples revealed that the fatigue failure at high amplitudes of testing was marked by extensive crack branching and the formation of secondary cracks.
A failure mechanism for this type of mixture was suggested and support by examining the internal structure of failed samples using X-ray CT.
With the help of SEM, FTIR and TGA, both the normal and failed samples of microwave ferrite phase shifter were selected, compared and analyzed.
This paper attempts to explain the observed LCF and CFI results based on the detailed metallography and fractography conducted on the failed samples.
