Study of ferrite formation in neutron irradiated austenitic stainless steels. Progress report, June 1, 1973--February 28, 1974
Description: A vibrating reed magnetometer was constructed for measurements on small irradiated samples. It can be operated at 4 to 500 deg K and can detect a magnetic moment of 4 x 10/sup -5/ erg/O/sub e/, with a signal-to-noise ratio of 20. A simple calibration procedure was devised. The magnetometer was used to measure magnetization curves of an irradiated type 316 austenitic stainless steel specimen at two different temperatures. Results confirm that the specimen contains numerous small magnetic particles which are presumed to be ferrite. Transmission electron microscopy of the irradiated specimen was not conclusive for the presence or absence of ferrite. (5 figures) (DLC)
