Abstract:

The author summarizes his research effort during the grant period. Included is the development of an infrared radiation temperature detection system for monitoring the temperature rise in thin-walled steel specimens loaded dynamically in a torsional Kolsky bar. Also included is a description of an investigation aimed at transforming AISI 1020 HRS under controlled conditions of prior austenite grain size, ferrite and pearlite grain sizes to reduce the size and number of carbide plates along the grain boundaries. The transformed material is to be used in a subsequent investigation into the influence of microstructure on the fracture toughness of 1020 HRS. Author
