Abstract:

Studies were made of various methods to develop a mondestructive test method for segregating receivers made from materials other than the specified resulphurized 8620H steel. Electromagnetic tests, distribution studies, spectrographic results, and metallurgical examinations of hardness and microstructure were made. The electromagnetic method gave excellent correlation with spectrographic results. Electromagnetic test method was recommended to segregate receivers made from materials other than the specified resulphurized 8620H steel. Test procedures are described, and results discussed.
